  • Publication number: 20210124118
    Abstract: A photonic edge coupler includes a slab waveguide and a ridge waveguide. The ridge waveguide includes a silicon wire waveguide, which includes a tapered portion. A first end of the slab waveguide is joined to the ridge waveguide at a junction, and a second end of the slab waveguide forms a first facet. The ridge waveguide defines a longitudinal axis that is associated with a direction of a light signal therein. The first facet is angled at less than 90 degrees relative to the longitudinal axis associated with the direction of the light signal therein. The first facet is disposed opposite to a laser facet associated with a laser waveguide. The longitudinal axis of the ridge waveguide defines a first center point, and the laser facet and the associated laser waveguide define a second center point. The second center point is laterally offset from the first center point.

  • Publication number: 20210101684
    Abstract: The present disclosure provides a swivel stop comprising a rotating member, a first boss coupled to the rotating member and a second boss coupled to the rotating member, and a second plate having a first interference surface and a second interference surface. An interference between the first boss and the first interference surface and the second boss and the second interference surface tends to limit the rotation of the rotating member with respect to the second plate. The swivel stop may further comprise a rail wherein the second plate is configured to translate along the rail.

  • Patent number: 10914821
    Abstract: A lidar system includes a light source to generate a frequency modulated continuous wave (FMCW) signal, and a waveguide splitter to split the FMCW signal into an output signal and a local oscillator (LO) signal. A transmit coupler provides the output signal for transmission. A receive lens obtains a received signal resulting from reflection of the output signal by a target. A waveguide coupler combines the received signal and the LO signal into a first combined signal and a second combined signal. A first phase modulator and second phase modulator respectively adjust a phase of the first combined signal and the second combined signal to provide a first phase modulated signal and a second phase modulated signal to a first photodetector and a second photodetector. A processor processes a first electrical signal and a second electrical signal from the first and second photodetectors to obtain information about the target.

  • Patent number: 10761836
    Abstract: At least one ALM artifact, indexed by a unified data store, that does not comply with at least one process convention can be identified. Responsive to identifying the ALM artifact, indexed by the unified data store, that does not comply with the process convention, a determination can be made by a process convention agent executed by a processor as to whether script code is available to update the ALM artifact to comply with the process convention. Responsive to the process convention agent determining that script code is available to update the ALM artifact to comply with the process convention, the process convention agent can automatically execute the script code to update the ALM artifact to comply with the process convention.
