Abstract: An electro-optic combiner includes a polarization splitter and rotator (PSR) that directs a portion of incoming light having a first polarization through a first optical waveguide (OW). The PSR rotates a portion of the incoming light having a second polarization to the first polarization to provide polarization-rotated light. The PSR directs the polarization-rotated light through a second OW. Each of the first and second OW's has a respective combiner section. The first and second OW combiner sections extend parallel to each other and have opposite light propagation directions. A plurality of ring resonators is disposed between the combiner sections of the first and second OW's and within an evanescent optically coupling distance of both the first and second OW's. Each of ring resonators operates at a respective resonant wavelength to optically couple light from the combiner section of the first OW into the combiner section of the second OW.

Abstract: A beam steering structure includes an alignment structure shaped to receive and align an optical fiber such that an axis of a core of the optical fiber is oriented in a first direction. The beam steering structure includes an end portion having an angled optical surface oriented at a non-zero angle relative to the first direction. The end portion is shaped and positioned so that light propagating along the first direction from the optical fiber passes through the end portion to reach the angled optical surface. A reflecting system is positioned on the angled optical surface across the first direction. The reflecting system is configured to reflect incident light propagating along the first direction into a first reflected beam of a first polarization and a second reflected beam of a second polarization. The first and second reflected beams are directed into first and second optical communication channels, respectively.

Abstract: An electro-optic receiver includes a polarization splitter and rotator (PSR) that directs incoming light having a first polarization through a first end of an optical waveguide, and that rotates incoming light from a second polarization to the first polarization to create polarization-rotated light that is directed to a second end of the optical waveguide. The incoming light of the first polarization and the polarization-rotated light travel through the optical waveguide in opposite directions. A plurality of ring resonators is optically coupled the optical waveguide. Each ring resonator is configured to operate at a respective resonant wavelength, such that the incoming light of the first polarization having the respective resonant wavelength optically couples into said ring resonator in a first propagation direction, and such that the polarization-rotated light having the respective resonant wavelength optically couples into said ring resonator in a second propagation direction opposite the first propagation direction.

Abstract: An intact semiconductor wafer (wafer) includes a plurality of die. Each die has a top layer including routings of conductive interconnect structures electrically isolated from each other by intervening dielectric material. A top surface of the top layer corresponds to a top surface of the wafer. Below the top layer, each die has a device layer including optical devices and electronic devices. Each die has a cladding layer below the device layer and on a substrate of the wafer. Each die includes a photonic test port within the device layer. For each die, a light transfer region is formed within the intact wafer to extend through the top layer to the photonic test port within the device layer. The light transfer region provides a window for transmission of light into and out of the photonic test port from and to a location on the top surface of the wafer.

Abstract: A photonic system includes a passive optical cavity and an optical waveguide. The passive optical cavity has a preferred radial mode for light propagation within the passive optical cavity. The preferred radial mode has a unique light propagation constant within the passive optical cavity. The optical waveguide is configured to extend past the passive optical cavity such that at least some light propagating through the optical waveguide will evanescently couple into the passive optical cavity. The passive optical cavity and the optical waveguide are collectively configured such that a light propagation constant of the optical waveguide substantially matches the unique light propagation constant of the preferred radial mode within the passive optical cavity.
