TOM 7 Thermal radiation and energy management

Active control of near-field radiative heat transfer in many-body systems

Philippe Ben Abdallah

Laboratoire Charles Fabry, CNRS, Institut d'Optique, France

Understanding and controlling the time evolution of thermal state of a system in nonequilibrium situation is of tremendous importance both on a fundamental and practical point of view. Many strategies have been implemented to date to actively control this evolution using an external driving.

In the first part of this talk I will describe the thermal relaxation of non-Hermitian many-body systems coupled to their environment subject to periodic drivings both in adiabatic limit and beyond this limit.

In the second part I will describe the dynamic control of thermal state of many-body systems and discuss some problems of practical interest such as the thermal targeting, insulation of some elements and the synchronization of local states during the relaxation process. I will also derive the conditions to fulfill in order to accelerate the relaxation process with a minimum energetic cost and to cool some elements with a minimum time.

Thermal radiation in dipolar many-body systems

Svend-Age Biehs

Oldenburg University, Germany

The framework of fluctuational electrodynamics for dipolar many-body systems is one of the working horse for theoretical studies of thermal radiation at the nanoscale which includes dissipation and retardation in a naturally way. Based on this framework I will discuss near-field thermal radiation in non-reciprocal and topological many-body systems. The appearance of the Hall and non-reciprocal diode effect for thermal radiation illustrates nicely the interesting physics in such systems as well as the edge mode dominated heat transfer in topological Su-Schrieffer-Heeger chains and a honeycomb lattices of plasmonic nanoparticles. In the latter, the theory allows for quantifying the efficiency of the edge-mode dominated heat transfer as function of the dissipation. Finally, I will present how the theoretical framework can be generalized to study far-field thermal emission of many-body systems close to an environment like a substrate, for instance. This theory might be particularly interesting for modelling thermal imaging microscopes.

Quantum levitation of photonic structures

Sol Carretero Palacios

Universidad Autónoma de Madrid, Spain

The Casimir-Lifshitz force originates from the quantum vacuum fluctuations of the electromagnetic field. This force is especially intense between interacting objects at nanoscale distances, and it can be attractive or repulsive depending on the optical properties of the materials (amongst other parameters). This fundamental phenomenon is at the heart of the malfunctioning of nano- and micro-electromechanical devices (NEMS and MEMS) that integrate many of the gadgets we use in our daily lives. Absolute control over these forces would make it possible to suppress adhesion and friction in these NEMs and MEMs. Here, we will show the possibility of controlling the Casimir-Lifshitz force by tuning the optical properties of the interacting objects. Specifically, we will present diverse examples of quantum levitation based on the Casimir-Lifshitz force of self-standing thin films comprising multilayer structures and films with spatial inhomogeneities (caused by imperfections, pores, inclusions, density variations, etc).

Casimir-Lifshitz force at the water-ice interface in the triple point: premelting of ice on a rock surface

Victoria Esteso


Herein we show a theoretical study about ice-premelting on a quartz rock surface based on calculations of the Casimir-Lifshitz force at that interface. In order to do that we consider a four-layer system composed of rock-ice-water-air. In contrast to previous investigations, which only considered variations of the thickness of either the water or the ice layer, here we analyse the equilibrium conditions of the system when both layers may vary their thickness. This enables multiple alternative equilibrium solutions stabilized in part by repulsive Casimir-Lifshitz interactions. Therefore, the final state of a system will depend on initial conditions and may explain variations in experimental measurements of ice-premelting.

In solar flat plate collectors, the high vacuum insulation suppresses the convective losses increasing the collector efficiency. The solar-to-thermal energy conversion efficiency in such solar thermal collectors is mainly defined by the optical and radiation losses of the selective solar absorber. We present the full process of design, optimization, fabrication, and characterization of multilayer coatings specifically thought for working in high vacuum flat solar thermal collectors at different operating temperatures, from 100 °C to 300 °C. We discuss the relative importance of absorptance and emittance in determining the collector thermal efficiency. The robustness of the performance of the coatings related to the unpreventable errors in layer thickness during the manufacturing stage is also considered through a genetic optimisation algorithm.

The prospect and use of passive radiative coolers for mitigating energy consumption have been and now even more so, attractive for sustainability and environmental conservation. Cellulose-based as well as other organic and inorganic materials have shown promising performance as passive coolers but most of these concepts lacked the capability to dynamically tune the extent of cooling.

In this work we demonstrate the electrical control of radiative cooling at ambient conditions enabled by tuning the thermal emissivity of a conducting polymer. We show that electrochemical redox switching provides clear temperature variations of the device when exposed to optical conditions resembling that of the cold night sky. Our results conclusively show that the observed variations in temperature are due to variations in radiative cooling. Thus, our study establishes a novel concept to dynamically tune a sustainable method to cool down objects via thermal radiation through the atmosphere and into cold space.

Aluminium microparticles have been proposed as a potential green energy vector, given their high energy density and the availability of clean recycling routes for the combustion products. Unfortunately, the phenomenology of micron-sized Al-air flames remains poorly understood. This contribution presents a new experimental setup and an optical model that can be used to study the fundamental properties of these flames, in order to design appropriate combustion systems. The radiative properties of the flame have been simulated by considering each burning Al particles as a core-shell particle, in which the cloud of condensed burning products is replaced with an effective medium. Emission from these alumina nanoparticles dominates the radiation profile and is required in order to better use pyrometric temperature measurements. This simplified model constitutes a starting point for more in-depth studies of heat transfer in Al/air flames.

We report a narrowband polarization-dependent reflectivity from Al-doped ZnO/ZnWO4 self-assembled eutectic composites in the mid-infrared range. Our results show a reflectivity modulation from 0.05 to 0.75 for two orthogonal polarizations of the incident field with a 10% Al concentration. Acting as natural polarizing filters these eutectic composites could open the way to the future development of low-cost photonics components in the IR.

The emerging interest in integrated optical technologies raises the need for precise characterisation techniques for waveguides presenting nonlinearities. Here we propose a non-interferometric measurement to accurately characterise the Kerr contribution in hybrid waveguides and illustrate its performances using SiN waveguides with a GSS chalcogenide top-layer. The sensitivity of our technique in terms of nonlinear phase reaches 10 mrad and its accuracy makes possible to extract the nonlinear contributions from the top-layer.

Mid-infrared quantum cascade lasers (QCLs) operating around 5.7 µm have been integrated with germanium waveguides on silicon substrates. QCL bars have been designed and fabricated at the University of Sheffield for the purpose of integration. This hybrid approach uses flip-chip technology that has been successfully transferred from a silicon-on-oxide (SOI) platform working at communication wavelengths, demonstrating the flexibility of this approach. Integration challenges are introduced, and solutions discussed, leading to the next iteration of design presented here.

The silicon-on-insulator (SOI) platform enables high integration density in photonic integrated circuits while maintaining compatibility with CMOS fabrication processes. Nevertheless, its inherently high modal birefringence hinders the development of polarization-insensitive devices. The dispersion and anisotropy engineering leveraging subwavelength grating (SWG) metamaterials makes possible the development of polarization agnostic waveguide components. In this work we build upon the bricked SWG metamaterial nanostructures to design a polarization independent 2×2 multimode interference (MMI) coupler for the 220 nm SOI platform, operating in the telecom O-band. The designed device exhibits a 160 nm bandwidth with excess loss, polarization dependent loss and imbalance below 1 dB and phase error lower than 5°.

Integrated optical phased arrays with circular architecture on a silicon platform

Daniel Benedikovic

University of Zilina, Slovak Republic

Optical phased arrays (OPAs) are now at the forefront of photonic research as a key beam steering technology for myriad of photonic applications, including in light detection and ranging (LIDAR), communications, and metrology, among others. Integrated OPAs with narrow beam widths and wide-angle steering are in critical need, especially for LIDARs in autonomous vehicle, drone and airplane navigation, or satellites. In this work, we numerically study the performances of OPAs having a circular layout arrangement. Compared to recently available solutions with 1D linear or 2D rectangular arrays, the proposed circular OPAs are poised to deliver effective suppression of the grating sidelobes, while improving beam steering range and obtaining narrower beamwidths. We demonstrate 110-element circular arrays with sidelobe suppression better than 10 dB and an angular beamwidth of 0.5°. Under a monochromatic operation at a 1550 nm wavelength, such array provides a solid angle steering range of 0.21π-sr, with a perspective for performance improvement by using large number of OPA elements and operating under broader spectral range.

Daniele Melati

Université Paris-Saclay, France

High performance and large-scale integration are driving the design of innovative photonic devices based on non-trivial shapes and metamaterials. In this scenario, multiple figures of merit must necessarily be considered in the evaluation of the device performance, e.g., losses, bandwidth, footprint, or tolerance to fabrication uncertainty. In this invited talk we will present our recent work on the use of machine learning and optimization tools for the development of photonic components with high performance and advanced functionalities.

1Ansys, Inc.; 2University of British Columbia; 3Cadence Design Systems, Inc.

The relentless need for higher bandwidth, lower power and lower cost data communications has driven tremendous innovation in integrated photonics in recent years. This innovation has been supported by state-of-the-art electronic-photonic design automation (EPDA) workflows, which enable process design kit (PDK) centred schematic driven design and layout, as well as statistically enabled electro-optical simulation. In addition, custom components can be introduced and optimized for a specific foundry process using advanced methods such as photonic inverse design and machine learning. While much of the innovation has been motivated by data communications, it has enabled a variety of different applications such as sensing, integrated LiDAR and quantum information technologies. We discuss the latest innovations in EPDA workflows and show how a silicon photonic ring-based wavelength demultiplexing (WDM) system can be easily designed, simulated and implemented. In addition, we discuss the extension of these workflows to support the design and simulation of quantum photonic devices, enabling designers to consider the effects of realistic sources and manufacturing imperfections when designing quantum building blocks to meet specific fidelity and fault tolerance thresholds.

Reconfigurable Optical Switches using phase-changing materials

Winnie N. Ye

Carleton University, Canada

We present the optical switches using phase changing cladding material. Two configurations of the optical switches will be investigated: one with serially-coupled microdisks and one with 2 x 2 Mach-Zehnder with dual suspended nanobeams. In this research, phase change material GSST is used to provide the stable cross and bar states corresponding to the amorphous and crystalline phases of the GSST, respectively. The unique integration of the switch design elements enables the nonvolatile resonant behavior, low switching power, low insertion loss and crosstalk, wide bandwidth, and fast switching times, for WDM switching applications. This work suggests an alternative switch configuration, in addition to the conventional thermo-optic and electro-optic switching in silicon photonics.
