Passive AWG-assisted Optical Phased Array for High-Resolution 2D Beam Scanning
A high-resolution 65-channel arrayed-waveguide-grating-assisted passive optical phased array is reported based on an ultra-low loss silicon nitride platform. Two-dimensional (2D) beam steering over 25°× 5° field-of-view was demonstrated through 100 nm laser wavelength tuning with 0.06° vertical resolution and beam divergence of 0.55°× 0.07°.
