Pierluigi Debernardi
Researcher, CNR IEIIT Torino

Pierluigi Debernardi received his degree in Electronics Engineering in 1987 from Politecnico di Torino, Torino, Italy. Since 1989 he's with the Italian National Council of Research at Politecnico di Torino. His interests are mainly in the field of the modelling of semiconductor materials and devices for optoelectronic applications. He studied especially III-V quantum wells, computing their optical response with Coulomb effects included on the basis of the second quantization approach. He was involved in ridge waveguide laser simulation, analysis of optical bistable behaviour of multiple quantum well devices, four-wave mixing in semiconductor oscillators and amplifiers. He has been working on microcavity lasers, and photonic band gap structures. The present research topics are Vertical Cavity Surface Emitting Lasers; in this field he's active in computing their electromagnetic properties to evaluate the spontaneous emission factor, threshold, static and dynamical properties and noise behaviour. Recently he is mostly involved in modelling and designing VCSEL structures with non-circular geometries. He proposed and optimized VCSELs with a dielectric grating integrated into the out-coupling section. In collaboration with Ulm University (Germany) such devices have been fabricated and prove to provide a stable polarization emission over all the operation range. He his author of about 50 papers on international reviews.
