Optical phased arrays in silicon on insulator for optical wireless systems

Hamdam Nikkhah, Karel Van Acoleyen, Roel Baets

Abstract

Optical phased array antennas (OPAs) have significant potential for optical beam steering, which has the application to high speed optical wireless links. In this paper, the characteristics of a two dimensional OPA with a structure composed of 2×2 and 4×4 antenna elements are verified. Beam steering by wavelength tuning of -0.16°/nm is measured and a required steering range of 1.97 ° is achieved within a -3dB coverage range of 5° in the theta direction and 7° in the phi direction.
