LICHTWELLENLEITER MIT ANGESCHLOSSENEM DETEKTOR

摘要

A light detector arrangement comprises three semiconductor layers, one on top of another, the center layer guiding the light and the layers on opposite sides of the center layer having a lower dielectric constant, the arrangement being provided with a first detector electrode on a side surface of the layers and a second detector electrode on the outer surface of one of the outer layers, and adjacent the first electrode.
