  • Publication number: 20200252126
    Abstract: Photonically integrated normal incidence photodetectors (NIPDs) and associated in-plane waveguide structures optically coupled to the NIPDs can be configured to allow for both in-plane and normal-incidence detection. In photonic circuits with light-generation capabilities, such as integrated optical transceivers, the ability of the NIPDs to detect in-plane light is used, in accordance with some embodiments, to provide self-test functionality.

  • Publication number: 20200233148
    Abstract: Methods and systems are presented for heterogeneous integration of photonics and electronics with atomic layer deposition (ALD) bonding. One method includes operations for forming a compound semiconductor and for depositing (e.g., via atomic layer deposition) a continuous film of a protection material (e.g., Al2O3) on a first surface of the compound semiconductor. Further, the method includes an operation for forming a silicon on insulator (SOI) wafer, with the SOI wafer comprising one or more waveguides. The method further includes bonding the compound semiconductor at the first surface to the SOI wafer to form a bonded structure and processing the bonded structure. The protection material protects the compound semiconductor from acid etchants during further processing of the bonded structure.

  • Publication number: 20200211923
    Abstract: The thermal impedance of p-i-n diodes integrated on semiconductor-on-insulator substrates can be reduced with thermally conducting vias that shunt heat across thermal barriers such as, e.g., the thick top oxide cladding often encapsulating the p-i-n diode. In various embodiments, one or more thermally conducting vias extend from a top surface of the intrinsic diode layer to a metal structure connected to the doped top layer of the diode, and/or from that metal structure down to at least the semiconductor device layer of the substrate.

  • Publication number: 20200209496
    Abstract: Described herein are photonic systems and devices including a optical interface unit disposed on a bottom side of a photonic integrated circuit (PIC) to receive light from an emitter of the PIC. A top side of the PIC includes a flip-chip interface for electrically coupling the PIC to an organic substrate via the top side. An alignment feature corresponding to the emitter is formed with the emitter to be offset by a predetermined distance value; because the emitter and the alignment feature are formed using a shared processing operation, the offset (i.e., predetermined distance value) may be precise and consistent across similarly produced PICs. The PIC comprises a processing feature to image the alignment feature from the bottom side (e.g., a hole). A heat spreader layer surrounds the optical interface unit and is disposed on the bottom side of the PIC to spread heat from the PIC.

  • Publication number: 20200132948
    Abstract: An optical coupling device can couple incident light from a fiber into waveguides, but can reduce the coupling of return light from the waveguides into the fiber. A Faraday rotator layer can rotate by forty-five degrees, with a first handedness, respective planes of polarization of incident beams, and can rotate by forty-five degrees, with a second handedness opposite the first handedness, respective planes of polarization of return beams. A redirection layer can include at least one grating coupler that can redirect an incident beam of one polarization so that the redirected path extends within the redirection layer toward a first waveguide, and can redirect an incident beam of an opposite polarization so that the redirected path extends within the redirection layer toward a second waveguide. An optional birefringent layer can spatially separate incident beam having different polarizations, so that two single-polarization grating couplers can be used.

  • Publication number: 20200008321
    Abstract: Photonic and electronic integrated circuits can be cooled using variable conductance heat pipes containing a non-condensable gas in addition to a phase-changing working fluid. To package the heat pipe with a subassembly including the integrated circuits in a standard housing providing a heat sink contact area, the heat pipe is oriented, in some embodiments, with its axis between evaporator and condenser ends substantially perpendicular to the direction along which the integrated circuit subassembly is separated from the heat sink contact area, and a portion of the exterior surface of the heat pipe is thermally insulated, with a suitable thermal insulation structure, from the heat sink contact area.

  • Patent number: 10505340
    Abstract: Described are various configurations of integrated wavelength lockers including asymmetric Mach-Zehnder interferometers (AMZIs) and associated detectors. Various embodiments provide improved wavelength-locking accuracy by using an active tuning element in the AMZI to achieve an operational position with high locking sensitivity, a coherent receiver to reduce the frequency-dependence of the locking sensitivity, and/or a temperature sensor and/or strain gauge to computationally correct for the effect of temperature or strain changes.
