We propose an electro-optic beam forming device using a two-dimensional array of patch-antennas embedded with orthogonal-gaps for wireless millimeter-wave signals. Two-dimensional beam angles of wireless millimeter-wave signals can be identified optically through electro-optic modulation.
We propose a new wireless millimeter-wave (MMW) to lightwave (LW) signal converter using an electro-optic crystal suspended to narrow-gap-embedded patch-antennas on a low-k dielectric substrate. Wireless MMW signals can be received by the patch-antennas and converted to LW signals by use of the MMW electric field across the narrow-gap for electro-optic (EO) modulation. An aperture area of the patch-antennas...
X-cut LiNbO3 microwave-lightwave converters using patch-antennas with a narrow-gap are proposed for direct wireless to optical conversion. Conversion efficiency of the proposed devices was improved by 6dB for 26GHz bands compared with z-cut LiTaO3 devices.
