Abstract

The use of a molecular beam epitaxy (MBE) engineered III-V semiconductor to quasioptically modulate a millimeter wave Gaussian beam is presented. The effect is based on the generation of excess carrier densities under photonic excitation of the material. Low light power densities are required due to the high recombination lifetime achieved in the used material. A modulation depth of more than 15 dB and a dark insertion loss of less that 0.5 dB has been obtained at 100 GHz.
