Selective filtering of confined optical waves in a straight waveguide coupled to a lateral stub

Yan Pennec, Maxime Beaugeois, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, L. Dobrzynski, Jean-Pierre Vilcot, Mohamed Bouazaoui, J.P. Vigneron

We report numerical simulations, based on a finite difference time domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. The incident wave which is of transverse magnetic polarization (TM) is either...

In situ epitaxial surface passivation of GaAlN/GaN HEMT heterostructures grown by LP-MOCVD

Marie-Antoinette Di Forte-Poisson, Nicolas Sarazin, M. Magis, Maurice Tordjman, Erwan Morvan, Raphaël Aubry, J. Di Persio, Bertrand Grimbert

This paper reports on in situ passivation studies of GaAlN/GaN High electron mobility transistors (HEMT) structures grown by low-pressure metalorganic vapour phase epitaxy (LP-MOVPE) on sapphire and silicon carbide substrates. GaN, GaAlN, AlN and AlN/GaN superlattice (SL) layers have been deposited...
