	3:30pm - 4:00pm Invited ID: 372 / OMN S01: 1 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Ultrafast control of conductivity with femtosecond lasers Davide Boschetto ENSTA Paris/Ecole Polytechnique/CNRS/Institut Polytechnique de Paris, France Femtosecond laser pulse irradiation enables precise control of conductivity in materials, revolutioniz- ing fields like nanoelectronics and materials science. It offers rapid modulation within femtosecond timescales, facilitating advancements in ultrafast electronics and high-speed data processing. In this talk, we will focus on the photoinduced reduction of conductivity in incommensurate crystals through excitation of electrons into localized states, revealing potential applications in optoelectronics, ultrafast switches, and photonic devices. 4:00pm - 4:15pm ID: 268 / OMN S01: 2 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Tuning mid-infrared polarization sensitive reflectivity in GaN/AlGaN heterostructures Alessandro Bile¹, Marco Centini¹, Daniele Ceneda¹, Adriana Passaseo², David Maria Tobaldi², Vittorianna Tasco², Concita Sibilia¹, Maria Cristina Larciprete¹ ¹Department of Basic and Applied Sciences for Engineering, Sapienza Università di Roma, Via Scarpa 16, 00161, Rome, Italy.; ²CNR NANOTEC Institute of Nanotechnology, Via Monteroni, 73100, Lecce, Italy. We present narrow-band polarization-sensitive reflectance of GaN/AlGaN heterostructures in the mid-infrared range. Experimental measurements performed at 15° angle of incidence show the excitation of a Berreman mode at the interface between GaN and sapphire substrate. A transfer matrix method for anisotropic layers has been used to analyze the obtained results. The contribution of the two-dimensional electron gas at the interfaces of the heterostructures has been included by proper modelization of an effective thin layer. 4:15pm - 4:30pm ID: 412 / OMN S01: 3 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Bound states in the continuum: from enhanced biosensing to upconversion emission Silvia Romano ISASI-CNR, Italy An overview of the applications of bound states in continuum (BICs) applications, from ultrasensitive sensing to giant enhancement of upconversion luminescence at Friedrich-Wintgen BIC, is reported. Perspective exploitation of this new class of devices is discussed. 4:30pm - 4:45pm ID: 276 / OMN S01: 4 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Laser-induced periodic surface structures as optical resonators for organic thin-film distributed feedback lasers Tiange Dong, Tobias Antrack, Jakob Lindenthal, Johannes Benduhn, Markas Sudzius, Karl Leo Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) and Institute of Applied Physics, TU Dresden, Germany Laser-induced periodic surface structures (LIPSS) have received considerable attention due to their potential for micro- and nanostructuring and surface functionalization of various materials. We present a novel application of LIPSS on a glass substrate as distributed feedback (DFB) laser resonators, capable of providing sufficient positive optical feedback to achieve lasing in thin-film waveguides with organic small molecules as a gain medium. The direct femtosecond micromachining allows for easy variation of the periodicity across a broad range of values, including those required to reach 1st Bragg order DFB operation. We investigate several small molecule organic thin-film systems and observe lasing in strong accordance with the underlying periodicities of all photonic structures involved. These results demonstrate the effectiveness of LIPSS as DFB laser resonators and suggest that they could facilitate the integration of organic thin-film media-based lasers and other photonic devices into various integrated photonic systems. 4:45pm - 5:00pm ID: 384 / OMN S01: 5 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Experimental determination of the thermal boundary resistance of carbon nanotubes in water: an ultrafast optical spectroscopy study Margherita Vittucci^1,2, Alessandro Casto¹, Fabien Vialla¹, Aurélien Crut¹, Concita Sibilia², Fabrice Vallée¹, Natalia Del Fatti¹, Francesco Banfi¹, Paolo Maioli¹ ¹FemtoNanoOptics group, Institut Lumière Matière, Université Lyon 1, CNRS, 69622, Villeurbanne; ²Dipartimento di Scienze di Base e Applicate per l’Ingegneria Sapienza Università di Roma, Via A. Scarpa 16, I-00161 Roma, Italy Thermal boundary resistance at the interface between carbon nanotubes and water is experimentally investigated measuring the nanotube cooling dynamics via ultrafast optical spectroscopy. This far-field non-contact technique allows quantitative measurement of the thermal boundary resistance and characterization of its dependence on the CNT size, the surrounding liquid and the specifics of the interface.
5:00pm - 6:30pm	OMN S02: Optoelectronic Nanotechnologies and Microsystems II Location: Musigny/Pommard/Volnay Session Chair: Emilija Petronijevic, Sapienza University of Rome, Italy Session Chair: Vito Mocella, CNR, Italy
	5:00pm - 5:30pm Invited ID: 522 / OMN S02: 1 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Nonlinear integrated quantum photonics with AlGaAs Sara Ducci Université Paris Cité, France Photonic quantum technologies are a promising platform for a large variety of applications ranging from secure long-distance communications to the simulation of complex phenomena. Among the material platforms under study, semiconductors offer a wide range of functionalities opening several opportunities for the development of integrated quantum photonic circuits. AlGaAs is particularly attractive to monolithically integrate active and passive components since it combines high second order nonlinearity, electro-optic effect and direct bandgap. In this talk, I will present the work of our team on the generation of quantum states of light in the telecom range with nonlinear AlGaAs chips working at room temperature. 5:30pm - 5:45pm ID: 155 / OMN S02: 2 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Light in memristive atomic scale junction - memristors go photonics Konstantin Malchow¹, Sarah Hamdad¹, Till Zellweger³, Bojun Cheng², Juerg Leuthold³, Alexandre Bouhelier¹ ¹Laboratoire Interdisciplinaire Carnot de Bourgogne CNRS UMR 6303, Université Bourgogne, F-21078 Dijon Cedex; ²Microelectronics Thrust, Function Hub, Hong Kong University of Science \& Technology, Guangzhou, China; ³ETH Zurich, Institute of Electromagnetic Fields, Zurich, 8092, Switzerland Memristive devices are an emerging new type of devices operating at the scale of a few or even single atoms. They largely exploited for emulating the electrical function of synapses and are thus currently investigated for performing in-memory and neuromorphic computing. In this contribution, we report the observation of a novel feature in these devices. We show that memristors can also emit photons during their activity. We identified three mechanisms producing photons with vastly different properties. The crossover between emission regimes depends on the history of the memristor and its operating conductance. Our results suggests that this new generation of memristor pave the way for multidimensional neural networks using both electrons and photons as information carrier. 5:45pm - 6:00pm ID: 382 / OMN S02: 3 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Ultrafast thermo-optical dynamics of plasmonic nanoparticles and carbon nanotubes Alessandro Casto, Margherita Vittucci, Michele Diego, Clément Panais, Romain Rouxel, Aurélien Crut, Noëlle Lascoux, Fabien Vialla, Fabrice Vallée, Francesco Banfi, Natalia Del Fatti, Paolo Maioli Institut Lumière Matière, Université Lyon 1, CNRS, Villeurbanne Femtosecond pump and probe optical spectroscopy has been employed for investigating ultrafast cooling of metal and carbon nano-objects, leading to quantitative determination of the physical parameters ruling thermal exchanges, such as thermal boundary resistance and thermal conductivity. Experimental and theoretical investigations on plasmonic nanoparticles and carbon nanotubes will be reviewed, as well as their applications to photoacoustics. 6:00pm - 6:15pm ID: 319 / OMN S02: 4 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Luminescent silicon nanowires for light-harvesting and environmental sensing applications Dario Morganti¹, Antonio Alessio Leonardi^2,3, Maria Jose Lo Faro^2,3, Patrizia Livreri⁴, Sabrina Conoci^1,5,6, Barbara Fazio⁶, Francesco Nastasi¹, Fausto Puntoriero¹, Alessia Irrera⁶ ¹Dipartimento di Scienze Chimiche, Biologiche, Farmaceutiche, ed Ambientali, Università Degli Studi di Messina, Viale Ferdinando Stagno d’Alcontres, 98166 Messina, Italy; ²Dipartimento di Fisica e Astronomia, Università di Catania, Via Santa Sofia 64, 95123 Catania, Italy; ³CNR-IMM UoS Catania, Istituto per la Microelettronica e Microsistemi, Via Santa Sofia 64, 95123 Catania, Italy; ⁴Department of Engineering, University of Palermo, Viale delle Scienze Ed.9, 90128 Palermo, Italy; ⁵CNR-IMM UoS Catania, Via Santa Sofia 64, 95123 Catania, Italy; ⁶URT LAB SENS, Beyond Nano—CNR, c/o Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, Viale Ferdinando Stagno d’Alcontres 5, 98166 Messina, Italy Silicon nanowires (Si NWs) represent one of the most promising platforms to be integrated into modern nanodevices. The fabrication of a dense array of vertically aligned ultrathin Si NWs using a low-cost, maskless approach and compatible with Si technology will be here demonstrated. Si NWs with efficient light emission at room temperature (RT) represent a great advance industry, paving the way for a wide range of unexpected photonic applications. In this work I will show the realization of a new hybrid material based on the luminescence of Si NWs and two different dyes for light-harvesting antennas applications, without any surface functionalization and with energy transfer efficiencies higher than 90%. The luminescence of Si NWs has also been used for sensing applications by the realization of highly sensitive sensors for the detecting of low concentrations of toxic gases. These sensors allow the detection of toxic gases below the threshold limits for human health, through both optical and electrical transduction. The achievement of light emission from silicon-based materials represents a revolution in the industrial field, as it paves the way for new Si applications. 6:15pm - 6:30pm ID: 473 / OMN S02: 5 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) Graphene/4H-SiC Schottky photodetector operating in the visible spectrum range Elisa Demetra Mallemace¹, Teresa Crisci², Mariano Gioffrè², Mario Medugno², Francesco Giuseppe Della Corte³, Sandro Rao¹, Maurizio Casalino² ¹Mediterranea University of Reggio Calabria, DIIES Dept., 89124 Reggio Calabria, Italy; ²National Research Council (CNR), ISASI Institute, 80131 Naples, Italy; ³University of Naples Federico II, DIETI Dept., 80125 Naples, Italy In this work, we present the first experimental results on a Schottky photodetector based on Silicon Carbide (SiC) and Graphene (Gr) designed to operate in the visible spectral range. While SiC has been extensively investigated for various applications in the ultraviolet domain, there are only a few works in the visible range, where SiC exhibits negligible optical absorption. To overcome such intrinsic limit of SiC, we exploit the properties of a single layer of Gr to enhance, significantly, the photodetection performance of the device operating, in our experiments, at the wavelength of λ=633 nm. From the current-voltage (I-V) characteristics, a series resistance of 3.7 kΩ, an ideality factor of 8.4, and the zero-bias Schottky barrier height of 0.755 eV have been calculated. Finally, the internal responsivity, as function of the reverse bias applied to the device, has been measured demonstrating a maximum value exceeding 1 mA/W at -5V. 6:30pm - 6:45pm ID: 552 / OMN S02: 6 Special Session on “Opto-electronic Nanotechnologies and Microsystems” (ONM) TMDs nanoparticles and 2D magnetic nanosheets for biomedical applications Carlo Altucci¹, Giulia Rusciano¹, Antonio Sasso¹, Chiara Feoli¹, Mohammadhassan Valadan¹, Manjot Singh¹, Jaber Adam¹, Jasneet Kaur¹, Carmela Dell’Aversana², Lucia Altucci², Mario Quarantelli¹, Maria Rosaria Del Sorbo² ¹Università degli Studi di Napoli Federico II, Italy; ²Università della Campania Luigi Vanvitelli, Italy You Two-dimensional nanomaterials, such as MoS2 nanosheets, have been attracting increasing attention in cancer diagnosis and treatment, thanks to their peculiar physical and chemical properties. Although the mechanisms which regulate the interaction between these nanomaterials and cells are not yet completely understood, many studies have proved their efficient use in the photothermal treatment of cancer, and the response to MoS2 nanosheets at the single-cell level is less investigated. Clearly, this information can help in shedding light on the subtle cellular mechanisms ruling the interaction of this 2D material with cells and, eventually, to its cytotoxicity. Here, as a first presented biomedical application of nanomaterials, we use confocal micro-Raman spectroscopy to reconstruct the thermal map of single human cancer cells targeted with MoS2 under continuous laser irradiation. The experiment is performed by analyzing the water O-H stretching band around 3,400 cm−1 whose tetrahedral structure is sensitive to the molecular environment and temperature. Compared to fluorescence-based approaches, this Raman-based strategy for temperature measurement does not suffer fluorophore instability, which can be significant under continuous laser irradiation. As a second biomedical application, we focus on preliminary obtained by the fabrication and use of magnetic nanomaterials in Magnetic Resonance Imaging, tested on 3D-printed phantoms.
