3-D integrable optoelectronic devices for telecommunications ICs

Mihai Adrian Ionescu, Luc Thévenaz, Philippe Renaud, Michel Declercq, Philippe Robert, Cyrille Hibert, Philippe Flückiger, Georges-André Racine

The design, fabrication and characterization of CMOS-compatible optoelectronic devices is discussed. All devices are fabricated on silicon on insulator (SOI) substrates which makes them suitable for three-dimensional (3-D) telecommunication photonic integr ...

A novel CMOS SOI unbalanced Mach-Zehnder interferometer: from design and simulations to fabrication and characterization

Mihai Adrian Ionescu, Luc Thévenaz, Philippe Renaud, Michel Declercq, Cyrille Hibert, Philippe Robert, Philippe Flückiger, Georges-André Racine

This paper reports on a novel, simple yet reliable, unbalanced SOI Mach-Zehnder (M-Z) interferometer architecture based on 1.2 μm CMOS process and adapted post-processing for the waveguide sidewalls. The fabricated electro-optical device is based on multip ...

New multichannel Ethernet protocol for passive optical star local area networks using coherent transmission

Philippe Robert, Christian Gaumier, Hector Garcia, Caroline Brisson

A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...

Etude des paramètres hétérogènes d'une surface active simulant une couronne d'éléments combustibles

Philippe Robert

In the method of the active surfaces a whole of nuclear fuel rods is described by a surface possessing suitable properties characterized in terms of 'heterogeneous parameters'. This study gives a calculus allowing the theoretical determination of the heter ...
