Research Interests

Our group is engineering the confinement of electrons and photons in small optical resonator cavities, for applications in communications, biology and nanotechnology.
Our projects involve design, modeling, and nanofabrication of lasers, in particular, Vertical Cavity Surface Emitting Lasers (VCSELs). We are developing new optical communication technologies with drastically enhanced performance enabling higher functionality systems.

Topics include: Semiconductor Vertical Cavity Lasers (VCSELs), Bio-photonics, Optical Communication, Nanofabrication, Optical Injection Locking, High-speed optical modulation.

Research Projects

Silicon On Insulator (SOI) based nanophotonicsSilicon waveguides using SOI substrate allow for the fabrication of extremely compact photonic circuits based on standard CMOS processing. The goal of this project is to simulate, design and characterize several highly attractive optical functions and sub-systems in silicon photonics.
