Abstract
An optical receiver including a photodetector and a waveguide is provided. The photodetector includes a plurality of photosensitive regions arranged in an array. The waveguide is disposed on the photodetector and includes a plurality of gratings, a plurality of optical channels, and a plurality of light-deflection elements. The gratings are respectively adapted to collect light beams incident on the waveguide at different angles. The optical channels are adapted to propagate the light beams collected by the gratings. The light-deflection elements are disposed on transmission paths of the light beams propagating in the optical channels and are located above the photosensitive regions. The light-deflection elements are adapted to propagate the light beams propagating in the optical channels to the photosensitive regions. An optical transceiver is also provided.
