Pierre Sansonetti

Title: Pierre Sansonetti: Innovator in Optical Devices and Semiconductor Lasers

Introduction

Pierre Sansonetti is a notable inventor based in Chatenay Nalabry, France. He has made significant contributions to the field of optical devices and semiconductor lasers. With a total of 2 patents, his work has advanced the technology in these areas.

Latest Patents

Sansonetti's latest patents include a "Process for the production of a monolithic integrated optical device" and a "Process for manufacturing a semiconductor laser having a buried ribbon." The latter patent describes a method where a double heterostructure is created on a substrate. In this process, a p-type doping material is implanted in the contact layer, rendering it amorphous. The unit, except for a ribbon, is etched to leave a mesa, and a resumption of epitaxy allows for the channel to be buried. This resumption does not lead to crystalline growth on the upper surface of the contact layer, although the annealing during this process results in good ohmic contacts at the level of the implanted layer.
