Antenna-Coupled-Electrode Electro-Optic Modulator for Converting 5G-Band Wireless Signal with Two Orthogonal-Polarization Field Components

Antenna-coupled-electrode electro-optic modulators for converting 5G-band wireless signals with two orthogonal-polarization components were developed and experimentally demonstrated utilizing the 4-antenas and 4-modulation electrodes combined structure. The measured polarization selectivity was over 25 dB in 5G-band.
