Abstract
D-band (110–170 GHz) antenna-coupled optical modulators with electro-optic (EO) polymer waveguides and non-coplanar patch antennas were fabricated using a poled EO polymer film transfer method. A carrier-to-sideband ratio (CSR) of 42.3 dB corresponding to an optical phase shift of 15.3 mrad was obtained by irradiating 150 GHz electromagnetic waves with an irradiation power density of 34.3 W/m2. Our devices and fabrication method have great potential for achieving highly efficient wireless-to-optical signal conversion in radio-over-fiber (RoF) systems.
