Antenna for a two-dimensional integrated Optical Phased Array designed for Optical Wireless Communications

Abstract

International audienceWe report on the design, fabrication and characterization of a silicon photonics based optical antenna producing a low divergence Gaussian beam. We measured a full width at half maximum (FWHM) of 1.40° along both directions. This antenna will be implemented as a unitary emitter in a two-dimensional optical phased array (2D-OPA) designed for directional optical wireless communication
