Classical and quantum light sources based on colloidal semiconductor nanocrystals

Francesco Di Stasio

Istituto Italiano di Tecnologia, Italy

Here I will present some recent application of semiconductor nanocrystals in optoelectronic devices such as light-emitting diodes (LEDs), and single photon emitters (SPEs). In particular I will focus on how III-V semiconductor nanocrystals such as InAs are promising candidates for RoHS complaiant near- infrared LEDs, and how the solution processing of colloidal nanocrystals can be exploited for the fabrication of small-footprint electrically driven SPEs.

Thermal effects reduction in a diode side-pumped rod-like bonded α-quartz||Nd:glass||α-quartz amplifying medium

Thomas Dubé1,2, Patrice Camy2, Sébastien Montant1

We present a numerical study of a square-shape rod-like bonded laser gain medium operating at 1053 nm. The sample is composed of a 5-mm thick Nd-doped phosphate glass bonded to two α-quartz crystals. Owing to this face cooling scheme, the heat generated in the gain medium is effectively reduced, hence resulting in less optical distortions. The simulation of the thermomechanical effects was conducted using COMSOL MultiPhysics® software. Transverse wavefront distortion and birefringence profiles were computed for a given pump mean power. Wavefront and birefringence measurements will be conducted on the bonded sample using a pump-probe setup which is discussed in this paper. These measurements will be presented and weighed with the numerical results.

Design and investigation of a low-threshold organic laser diode using mixed-order DFB cavities

Yara El Droubi, Quentin Gaimard, Jeanne Solard, Mahmoud Chakaroun, Azzedine Boudrioua

Université Sorbonne Paris Nors, France

In this work, we experimentally and theoretically investigate the optical and electrical optimization of an OLED associated to a mixed-order DFB cavity. We, firstly focus on the design and the fabrication of a mixed-order DFB cavity with a high quality factor. We particularly study the impact of the deposition of the organic layers on the topology and the quality factor of the cavity.

Organophosphorus emitters for OLEDs

Muriel Hissler1, Pierre-Antoine Bouit2, Denis Tondelier3, Bernard Geffroy4

1University of Rennes 1, France; 2University of Rennes 1, France; 3Ecole Polytechnique; 4Ecole Polytechnique

In this paper, we present the development of OLEDs using organophosphorus derivatives as emitters. In this study, we were able to show that the structural variations carried out on phospholes, phosphinines and phosphepines (functionalization of the phosphorus atom, nature of the substituents) make it possible to modulate the emission wavelengths and, thus, the emission colour of the diodes. Using this concept, we were able to develop TADF and chiral organophosphorus emitters and hybrids emitting at different wavelengths which can be used for the development of OLEDs. The diode structures used are simple and provide high external quantum yields



9:45am - 10:00am

Simultaneous oscillation of dual optical parametric oscillators on monolithic chi(2) nonlinear photonic crystals

KaiHsun Chang1,2, ChiaChun Fan1, MingShung Tsai1, FuHsiang Yang1, Safia Mohand Ousaid2, Azzedine Boudrioua2, LungHan Peng1

1National Taiwan University, Taiwan; 2Université Paris 13, France

Simultaneous oscillation of two pairs of signals and idlers was demonstrated. We also showed the efficiency of the sum frequency generation of two idlers was comparable with second harmonic generation of each idler. Our design shows the potential of building multi-wavelength laser source from UV to NIR on monolithic crystal.
