Abstract: This disclosure provides systems, methods, and apparatus for a photonic chip. The photonic chip includes one or more electronic components in addition to one or more optical components. An optical coupler can be utilized for coupling external optical fibers or sources with the optical components. The optical coupler can include a beam splitter for splitting an incident light having both trans-electric (TE) and trans-magnetic (TM) polarizations into two beams having only TE and TM polarizations. The light beam with TM polarization is incident on a grating coupler on the chip having a horn section, which includes gratings. The light beam is reflected onto the grating coupler such that the direction of TM polarization is within the first plane of incidence, and the first beam of light is incident on the first plurality of gratings at an angle with respect to a normal to the plane of the first grating coupler.

Abstract: The present disclosure discusses an improved optical transceiver. The optical transceiver of the present disclosure includes an optical transmitter and an optical receiver that are spatially separated. In some implementations, the optical receiver and optical transmitter are staggered from one another. Each of the optical receiver and the optical transmitter and housed within a separate optical lens. In some implementations, the separation of the components reduces mechanical, thermal, and electrical cross talk between the optical transmitter and the optical receiver. The separation of the components can also ease the constraints of the optical alignment between the optical transmitter and the optical receiver and each of their respective lenses.

Abstract: Systems and methods for increasing bandwidth in a computer network are provided. A computer network can include a first lower level switch, first and second upper level switches, and first and second passive optical splitters, and a mirror. The first passive optical splitter can have a first port directly coupled to the first upper level switch, a second port directly coupled to the second upper level switch. The second passive optical splitter can have a port directly coupled to a port of the first passive optical splitter, and a port directly coupled to the first lower level switch. The mirror can be coupled to a port of the second passive optical splitter and reflect an optical signal received from the second passive optical splitter to the first upper level switch and second upper level switch through the second passive optical splitter and the first passive optical splitter.
