  • Patent number: 10613279
    Abstract: A structure to couple light to a waveguide is described. In an example, a light source of the structure may emit light from an emission point towards a lens of the structure. The light source may be disposed at a location such that the emission point of the light source is offset from a center of the lens. The lens may be integrated in a substrate of a structure comprising the light source. The lens may refract the light emitted from the emission point at an angle. The angle may be based on the offset between the emission point and the center of the lens. The structure may couple the refracted light to a coupler of the waveguide at an incident angle.

  • Patent number: 10608410
    Abstract: The embodiments herein describe a single-frequency laser source (e.g., a distributed feedback (DFB) laser or distributed Bragg reflector (DBR) laser) that includes a feedback grating or mirror that extends along a waveguide. The grating may be disposed over a portion of the waveguide in an optical gain region in the laser source. Instead of the waveguide or cavity being linear, the laser includes a U-turn region so that two ends of the waveguide terminate at the same facet. That facet is coated with an anti-reflective (AR) coating.

The electro-optic modulator comprises at least one upstream modulation subunit, at least one downstream modulation subunit and at least one phase-matching unit. The upstream and downstream modulation subunits are optically connected in series such that the optical radiation passes the downstream modulation subunit after passing the upstream modulation subunit. An electrical upstream modulation signal may be applied to the upstream modulation subunit, and an electrical downstream modulation signal may be applied to the downstream modulation subunit. The phase-matching unit is configured to delay the downstream modulation signal such that a phase difference between the upstream modulation signal and the downstream modulation signal is minimal.

  • Patent number: 10551561
    Abstract: An optical subassembly includes a planar dielectric waveguide structure that is deposited at temperatures below 400 C. The waveguide provides low film stress and low optical signal loss. Optical and electrical devices mounted onto the subassembly are aligned to planar optical waveguides using alignment marks and stops. Optical signals are delivered to the submount assembly via optical fibers. The dielectric stack structure used to fabricate the waveguide provides cavity walls that produce a cavity, within which optical, optoelectronic, and electronic devices can be mounted. The dielectric stack is deposited on an interconnect layer on a substrate, and the intermetal dielectric can contain thermally conductive dielectric layers to provide pathways for heat dissipation from heat generating optoelectronic devices such as lasers.
