Publication number: 20220019029Abstract: An optical coupler couples light from waveguides of a photonic integrated circuit (PIC) to output waveguides, for example waveguides of a planar lightwave circuit (PLC). The optical coupler includes optical elements having different optical properties. In some embodiments the optical properties vary to account for waveguide angled facets in the PIC, and in some embodiments the optical properties vary to account for the PIC being mounted at an angle compared to the PLC, or optical coupler.Type: ApplicationFiled: March 1, 2021Publication date: January 20, 2022Inventors: Bardia Pezeshki, Ramsey Selim, John Heanue, Hindrik Bulthuis, Susannah Heck

Publication number: 20210349272Abstract: An optical transceiver may include a circuit board, lasers, and a PLC including optical multiplexers and demultiplexers. The PLC may be coupled to fiber optic lines at a forward edge of the PLC, with a rear edge of the PLC receiving light for transmission generated by the lasers. Light received at the forward edge of the PLC may be demultiplexed into data channels and routed to a top surface of the PLC for optoelectronic conversion by photodetectors. In some embodiments each data channel is routed into a corresponding plurality of waveguides, with each of the corresponding plurality of waveguides providing light to the same photodetector. In some embodiments at least some receive side electronic circuitry, other than photodetectors, is stacked on top of the PLC.Type: ApplicationFiled: December 17, 2020Publication date: November 11, 2021Inventors: Bardia Pezeshki, Hindrik Bulthuis, Ramsey Selim, Andrew Grant, Lucas Soldano, Owen Shea, Josef Wendland, Jamie Stokes, Suresh Rangarajan, Josh Oen, Ron Zhang, Rob Kalman, Drew Lundsten

Patent number: 10684415Abstract: Roughly described, an integrated optical device includes both a PLC chip and an attached SiPh chip. The PLC chip has a PLC waveguide which terminates at an end facet. The SiPh chip has a SiPh waveguide which includes a Bragg grating which diffracts light from the SiPh waveguide toward the PLC chip. The PLC chip also has a turning mirror to reflect light emitted from the Bragg grating onto the end facet of the PLC waveguide. The Bragg grating is designed to direct light emitted from the Bragg grating into the end facet of the PLC waveguide so that after reflecting off the turning mirror the light focuses within one Rayleigh distance of the end facet of the PLC chip.Type: GrantFiled: December 5, 2016Date of Patent: June 16, 2020Assignee: Broadex Technologies UK LimitedInventors: Hindrik Freerk Bulthuis, Lucas Soldano, Ramsey Selim
