    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.

    Abstract: An optical component optically coupled to an optical fiber includes a substrate and an edge-emitting laser. The substrate includes an accommodating cavity, a plurality of openings, a waveguide, an optical coupler and a plurality of pads. The waveguide and the optical coupler are distributed outside the accommodating cavity. The openings are distributed at the bottom surface of the accommodating cavity and the pads are located at the bottom of the openings. The optical coupler is optically coupled to an end of the waveguide and includes a light-incident surface. The edge-emitting laser is embedded in the accommodating cavity and includes a light-emitting layer and a plurality of bumps located in the openings and electrically connected to the pads. The ratio of the level height difference between the light-emitting layer and the optical coupler to the thickness of the optical coupler ranges from 0 to 0.5.

    Abstract: An optical element includes a substrate, a first insulating layer, a first optical waveguide layer, a first edge coupler, and a first micro-optical element. The first insulating layer is disposed on the substrate. The first optical waveguide layer is disposed on the first insulating layer to transmit a light beam. The first edge coupler is disposed on the first insulating layer and coupled to an end of the first optical waveguide layer. The first micro-optical element is disposed on the substrate and includes a first inclined surface. The first micro-optical element is located within a first groove formed between the substrate, the first insulating layer, the first optical waveguide layer, and the first edge coupler. The light beam is sequentially transmitted from the first optical waveguide layer to the first edge coupler, emitted from the first edge coupler, and reflected by the first inclined surface to an optical fiber connector.
