Paper Abstract

A scheme of applying high contrast grating hollow waveguide (HCG-HW) to optical phased array (OPA) as the transmission waveguide and phase shifter is proposed. The phase shift with varied HCG-HW dimensions is deduced in a theoretical approach and demonstrated by the simulation results. Beam steering in one direction is done by varying the wavelength. A phase shift range of 18.7 rad and the beam angle shift to 12.62° with varied wavelengths are presented.
