Abstract :
Millimeter-wave space-division-multiplexing signals were discriminated by a newly-developed electro-optic modulator using an array of antenna-coupled electrodes and polarization-reversed structures of ferroelectric optical crystals. Channel isolation over 13dB was obtained for two 38GHz wireless signals with an irradiation angle difference of 15 degrees by use of a fabricated device 30mm in length. In this paper, the device structure, operation principle, analysis, and experimental demonstrations are presented.
