Abstract: An electro-optical chip includes an optical input port, an optical output port, and an optical waveguide having a first end optically connected to the optical input port and a second end optically connected to the optical output port. The optical waveguide includes one or more segments. Different segments of the optical waveguide extends in either a horizontal direction, a vertical direction, a direction between horizontal and vertical, or a curved direction. The electro-optical chip also includes a plurality of optical microring resonators is positioned along at least one segment of the optical waveguide. Each microring resonator of the plurality of optical microring resonators is optically coupled to a different location along the optical waveguide.

CPC classification number: G02B6/2934 , G02B6/12007
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.

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 thermo-optic phase shifter includes a substrate having a cavity formed into an upper region of the substrate. The thermo-optic phase shifter includes an optical waveguide disposed above the substrate. The optical waveguide extends across and above the cavity. The thermo-optic phase shifter also includes a heater device disposed along a lateral side of the optical waveguide. The heater device extends across and above the cavity. The cavity is formed by an undercut etching process after the optical waveguide and the heater device is formed. The optical waveguide can be formed to include one or more segments that pass over the cavity. Also, a second heater device can be included such that the one or more segments of the optical waveguide that extend over the cavity are bracketed by heater devices. Thermal transmission structures can be included to enhance heat transfer between the heater device(s) and the optical waveguide.

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 grating coupler reflector (retro reflector) is formed within a photonics chip and includes a vertical scattering region, an optical waveguide, and a reflector. The optical waveguide is optically coupled to the vertical scattering region. The reflector is positioned at an end of the optical waveguide. The reflector is configured to reflect light that propagates through the optical waveguide from the vertical scattering region back toward the vertical scattering region. The location of the grating coupler reflector on the photonics chip is determinable by scanning a light emitting active optical fiber over the chip and detecting when light is reflected back into the active optical fiber from the grating coupler reflector. The determined location of the grating coupler reflector on the photonics chip is usable as a reference location for aligning optical fiber(s) to corresponding optical grating couplers on the photonics chip.
