Abstract :
In this paper, a simple high contrast optical modulator that uses the Franz-Keldysh (FK) effect in a thin film of H+ implanted GaAs integrated in an asymmetric Fabry-Perot (ASFP) device is reported. As we discuss, this approach might offer a simpler approach to high speed optical modulation and bistability. A schematic of the device structure, fabricated using standard photolithography and selective wet etching, is presented. The ASFP consists of a high reflectivity silver and a low reflectivity ITO mirror
