In this research project, a new microwave/ millimeter-wave to lightwave converter utilizing electro-optic modulation with polarization reversed structures has been proposed and developed. The proposed device has several advanced functions/ characteristics : receiving multiple wireless signals coming from different directions simultaneously and converting them into different optical signals according to their injection angles, low noise, low cross-talk, low-power consumption, light weight and applicable to the space-division-multiplexing technology for broadband wireless communication systems. In the three-year research, a new device operating around 40GHz was designed and fabricated, and the basic performances were experimentally demonstrated. The wireless space channel isolation was obtained over 13dB at 38GHz. The carrier to noise ratio in the re-converted 38GHz signal was over 25dB.
