The effect of waveguide parameters on gan based S-bend Y-junction optical power divider

Retno Wigajatri Purnamaningsih, N.R. Poespawati, Tomy Abuzairi, Sasono Rahardjo, Maratul Hamidah, El Hadj Dogheche

GaN-based structures have attracted many researchers in developing photonic devices. These semiconductor structures can operate at high temperatures and high-power levels due to their mechanical hardness. So far, optical splitters design based on Y-junction splitters are widely used on the various…

Transformational fluctuation electrodynamics: application to thermal radiation illusion

Ahmed Alwakil, Myriam Zerrad, Michel Bellieud, Denis Veynante, Franck Enguehard, Nathalie Rolland, Sebastian Volz, Claude Amra

Thermal radiation is a universal property for all objects with temperatures above 0K. Every object with a specific shape and emissivity has its own thermal radiation signature; such signature allows the object to be detected and recognized which can be an undesirable situation. In this paper, we…

III-nitrides based electro-optic modulators

Bandar Alshehri, Mohammed El Gibari, Li Hong Wu, Dimitri Pavlidis, El Hadj Dogheche

III-nitride materials deposited on sapphire and silicon, are considered mature semi-conductorsfor applications in photonics and optoelectronics. Unlike highly temperature sensitive optical waveguides made on more traditional materials such as InP, Gallium Nitride (GaN) is a good candidate for…

AlN-based HEMTs grown on silicon substrate by NH3-MBE

Stephanie Rennesson, Fabrice Semond, M. Nemoz, Jeans Massies, Stéphane Chenot, Ludovic Largeau, Ezgi Dogmus, Malek Zegaoui, F Medjdoub

In this paper, AlN-based HEMTs on silicon are demonstrated using NH3-MBE. The spirit is to get the highest 2DEG density theoretically achievable in nitrides while keeping thin barrier thickness, which is mandatory to achieve high frequency performances. To do that, the strategy consists in growing…

Advances in silicon surface texturization by metal assisted chemical etching for photovoltaic applications

Sylvain Le Gall, Raphaël Lachaume, Encarnacion Torralba, Mathieu Halbwax, Vincent Magnin, Taha El Assimi, Marin El Fouchier, Joseph Harari, Jean-Pierre Vilcot, Christine Cachet-Vivier, Stéphane Bastide

— New Si processes based on Metal Assisted Chemical Etching (MACE) are explored for solar cells texturization. Pt and Au are considered as catalysts for MACE of p and n-type Si substrates. 2D band bending modeling at the nanoscale shows that Pt nanoparticles (NPs) make ohmic contacts and induce…
