The dark exciton ground state promotes photon-pair emission in individual perovskite nanocrystals

Philippe Tamarat, Lei Hou, Jean-Baptiste Trebbia, Abhishek Swarnkar, Louis Biadala, Yann Louyer, Maryna I Bodnarchuk, Maksym V Kovalenko, Jacky Even, Brahim Lounis

Cesium lead halide perovskites exhibit outstanding optical and electronic properties for a wide range of applications in optoelectronics and for light-emitting devices. Yet, the physics of the band-edge exciton, whose recombination is at the origin of the photoluminescence, is not elucidated. Here…

Thermophone or the future of ultrasound transducers: Modelling of thermoacoustics generation in porous materials

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat, Zhi Lin Ngoh, Dunlin Tan, Edwin Hang Tong Teo, Philippe Coquet

Electroacoustic transducers along with piezoelectric devices are the most widely used methods for acoustic sound generation in gas and liquids. A mechanical movement of a membrane induces fluid vibration thus creating an acoustic wave. The thermoacoustic process on the other hand uses fast paces…

Miniaturization of Transmission Lines: Meandered Slow-wave CPWs

Marc Margalef-Rovira, Tadeu Mota Frutuoso, Abdelhalim Saadi, Loïc Vincent, Manuel J. Barragan, Emmanuel Pistono, Christophe Gaquière, Philippe Ferrari

This work presents novel transmission line structures based on Meandered Slow-wave CoPlanar Waveguides (MS-CPWs), aiming to achieve high miniaturization. As a proof-of-concept, these two kinds of transmission lines were designed and fabricated in the AMS 0.35 mu m CMOS technology together with…

Polymer Photonic Crystal Membrane for Human Body Thermoregulation

Mohamed Boutghatin, Salim Assaf, Michèle Carette, V. Thomy, Abdellatif Akjouj, Bahram Djafari-Rouhani, Yan Pennec

We study the optical properties of a polymer photonic membrane to keep the human body in thermal comfort. We show theoretically that the periodic structuration of the membrane with air holes modulates the optical response in the Mid-Infrared range. We found that the modulation of the optical…
