An active microphotodiode array of oscillating pixels for retinal stimulation

Philippe Renaud, Mihai Adrian Ionescu, Olof Pontus Linderholm, Marco Mazza

We have developed an active microphotodiode array (MPDA) for retinal stimulation. The unique feature of the device is that each pixel acts as an independent oscillator, whose frequency is controlled by the incident light intensity. The design is based on a ...

3-D integrable optoelectronic devices for telecommunications ICs

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

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

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

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 ...
