Chip-Scale Optical Phased Arrays with Ta Nanostructures

Abstract

We present results on the design and simulation of optical phased arrays made with Si waveguides and Ta scattering elements. We show that multi-element apertures offer advantages in varying the output power level and beam shape, and then demonstrate narrow beams that can be steered by tilde20 degree with thermo-optic tuning.
