  • Publication number: 20240295694
    Abstract: A system, method, and photonic chip for an optical circulator are described. The system includes a first polarization splitter, a first optical circuit, and a first controller. The first polarization splitter receives, at a first port of the first polarization splitter, a first optical signal. The first optical circuit is optically coupled to the first polarization splitter. The first optical circuit includes a first plurality of phase shifters. The first optical circuit receives, at a first port of the first optical circuit, a second optical signal. The first controller adjusts the first plurality of phase shifters such that the first optical circuit outputs the first optical signal at a second port of the first optical circuit and such that the first polarization splitter outputs the second optical signal at the first port of the first polarization splitter.

  • Publication number: 20240272382
    Abstract: Embodiments herein describe a pluggable module that includes a ROADM implemented in a photonic integrated circuit (PIC). By implementing the ROADM in a PIC, the ROADM can be placed on smaller, pluggable modules (e.g., a Small Form-factor Pluggable (SFP) which can be a hot-pluggable network interface module).

  • Publication number: 20240272369
    Abstract: Embodiments herein describe using an actuator to tune a waveguide. In one embodiment, the tunable waveguide includes a gap between the waveguide and cladding. The actuator can compress the cladding to shrink this air, bringing the cladding closer to the waveguide. Doing so changes the effective refractive index of the waveguide. Alternatively or additionally, the actuator can increase the gap.

  • Patent number: 12044884
    Abstract: Solder reflow compatible connections between optical components are provided by use of reflow compatible epoxies to bond optical components and remain bonded between the optical components at temperatures of at least 260 degrees Celsius for at least five minutes. In some embodiments, the reflow compatible epoxy is index matched to the optical channels in the optical components and is disposed in the light path therebetween. In some embodiments, a light path is defined between the optical channels through at least a portion of an air gap between the optical components.

  • Patent number: 11784175
    Abstract: An optoelectronic assembly and methods of fabrication thereof are provided. The assembly includes a mold compound; a photonic integrated circuit (PIC) embedded in the mold compound, that has a face exposed from the mold compound in a first plane; an interposer embedded in the mold compound, that has a face exposed from the mold compound in the first plane (i.e., co-planar with the exposed face of the PIC); and an electrical integrated circuit (EIC) coupled to the exposed face of the PIC and the exposed face of the interposer, that establishes bridging electrical connections between the PIC and the interposer.

  • Patent number: 11762155
    Abstract: Embodiments herein describe an optical system that includes a photonic integrated circuit (PIC) bonded to a package containing an electrical integrated circuit (EIC). However, this bond can prevent an edge coupler from optically aligning an optical fiber to an edge of the PIC in order to transfer optical signals. To provide room for the edge coupler, the PIC is arranged to overhang the package containing the EIC so that the package does not interfere with the ability of the edge coupler to align with the side or edge of the PIC. In this manner, an optical fiber can be optically aligned (e.g., butt coupled) to the edge of the PIC rather than having to use a grating coupler or some other less efficient optical coupling in order to transfer optical signals between the PIC and the optical fiber.
