A photonic integrated spatial mode controller was demonstrated, which consisted of a 100-channel arrayed-waveguide-grating (AWG), phase and amplitude modulator array reflector based on the thin-film z-cut lithium niobate platform. The fabricated chip exhibited narrow channel interval about 50 pm. measured response time Mach-Zehnder interferometer (MZI) is less than 0.5 us.
