The optical technique offers unique advantages in 1 near perfect isolation between controlling and controlled devices, 2 elimination of RF feeds in a large array systems, 3 immunity from electromagnetic interference, 4 light weight and compact size, 5 extremely fast response, 6 high power handling capability, and 7 amendability to monolithic integration. The results are summary of the investigation of a number of millimeter wave device concepts based on laser induced solid state plasma in semiconductors. The generation and control of millimeter wave and microwaves by optoelectronic techniques are reported. Complete time synchronization between Radiofrequency and optical signals is achieved. Laser controlled phase shifters, switches and modulators at 94 GHz are described. Keywords Waveguides, Millimeter wave, Optical control, Phase shifter.
