Abstract
A high-resolution 64-channel arrayed-waveguide-grating-assisted silicon-nitride integrated optical phase array is demonstrated for 2-D beam steering. A field of view of 5° ×25° with 0.3° vertical resolution is achieved over a wavelength range of 100 nm with a single optical input. Higher vertical resolution can be attained by utilizing all the inputs of the OPA.
