Beschreibung
Zusammenfassung:	A modulator for modulating light from a light source in dependence on a received electrical signal. The modulator is configured with a membrane structure and comprising a plurality of semiconductor layers doped in a region within the membrane structure to form a semiconductor junction. A layer of dielectric material is disposed between the semiconductor junction and a base substrate of the modulator. L'invention concerne un modulateur pour moduler la lumière provenant d'une source de lumière en fonction d'un signal électrique reçu. Le modulateur est conçu avec une structure de membrane et comprend une pluralité de couches semi-conductrices dopées dans une région à l'intérieur de la structure de membrane pour former une jonction semi-conductrice. Une couche de matériau diélectrique est disposée entre la jonction semi-conductrice et un substrat de base du modulateur.
