Paper Abstract

An array of grating couplers is studied to be used for beam steering in a wireless optical communication system. This structure is designed using a rib waveguide with a silicon thickness of 220nm and an etch depth of 70nm using 2μm silica substrate. TE polarized input light with wavelength of 1550nm is coupled into the feed waveguide. The structure is optimized based on the angular coverage, directed power, and beam efficiency of the radiated main beam of an individual grating coupler. The main beam radiated by optimized grating coupler has a beamwidth of 10.3°×30.7°. The designed 1-D array of the fifteen grating couplers provides tunability in the range of around 30 degrees which is required for a point to pint wireless optical communication transmitter.
