We proposed an optically controlled phased array antenna using a spatial light modulator for an adaptive satellite communications system. We have developed a prototype of an Optical Beam Forming Network, which enables control of 2 beams individually, and demonstrated at Ka band. We confirmed a good agreement between theoretical antenna patterns and calculated antenna patterns, which are simulated...
Polarization insensitivity of InAs/GaAs quantum dot optical amplifier has been demonstrated by controlling dot shape. This polarization insensitivity covers a bandwidth in excess of 40 nm.
