Abstract
In order to operate at high frequencies and at high optical powers without reducing the possible depth of modulation, a quantum well electro-optical modulator has a semiconductor structure of III-V elements including, in succession, an n doped layer, an undoped layer, a quantum well active layer and a p doped layer. Applications include optical transmission systems.
