Photonics Based Microwave Hybrid Coupler With Tunable Coupling Ratio and Phase Difference
A new microwave hybrid coupler that solves the problems of limited bandwidth and reconfigurability in conventional couplers, is presented. It is based on a bi-directional operating optical phase modulator and an optical signal processor to control the amplitude and phase of the phase modulated optic...
