Wireless space-division-multiplexed signal discrimination device using electro-optic modulator with antenna-coupled electrodes and polarization-reversed structures

摘要

Millimeter-wave wireless 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. Discrimination with channel isolation over 13 dB was obtained for two 38 GHz wireless signals with an irradiation angle difference of 15° by use of a fabricated device 30 mm in length.
