Abstract

We present a review of our recent work at WaveBand Corporation on optically controlled millimeter wave (MMW) steering antennas. Instead of relying on photonically controlled discreet microwave elements like phase-shifters, modulators, photodiodes, etc., our approaches are based on the interaction of MMWs with an electron-hole plasma grating created by optical means. We use silicon wafers as a medium for plasma recording as well as for plasma-MMW interaction. Electron-hole plasma is generated by illuminating the silicon wafer with near IR or visible light. The required plasma pattern is created by using a spatial-light- modulator, a set of photo-masks, or an optical fiber array connected to individually controlled LEDs. The new architectures promise flexible antenna designs and a cost reduction sizable enough to compare the proposed antennas with their phase-array counterparts.
