  • Publication number: 20210036481
    Abstract: Processes and apparatuses described herein provide for an efficient cyclical fiber-optic connection between a source component and multiple destination components in a computing environment. A comb laser generates a laser signal that includes laser light of a first frequency that is red-shifted from a carrier frequency. The comb laser concurrently transmits the laser signal to four ring resonators via an optical waveguide. Three of the ring resonators are initially configured for optical resonance at a second frequency that is blue-shifted from the carrier frequency, while one of the ring resonators is initially configured for optical resonance at the first frequency. The laser signal is modulated to communicate data to a first target location associated with the ring resonator that is initially configured for optical resonance at the first frequency.

  • Patent number: 10897119
    Abstract: Techniques and circuitry for a semiconductor laser with enhanced lasing wavelengths stabilization are described. A semiconductor laser can generate an optical signal (e.g., single or multi-wavelength), for use in a Dense Wavelength Division Multiplexing (DWDM) interconnect system. The stabilization circuitry can include temperature sensor circuitry that measures an operational temperature of the semiconductor laser, and a feedback controller that can determine a temperature-induced wavelength shift that may be experienced by the multi-wavelength optical signal based on the laser's temperature. The feedback controller is also configured to generate a compensation signal that is determined to cause a complimentary shift in the multi-wavelength optical signal, where the complimentary shift can compensate for the temperature-induced wavelength shift.

  • Patent number: 10884192
    Abstract: Examples herein relate to single-etch layer grating couplers. In particular, implementations herein relate to single-etch layer grating couplers comprising a planar waveguide wherein a first grating section and a second grating section are etched into. The first grating section is configured to scatter light at a given wavelength at a first angle relative to vertical and the second grating section is configured to scatter light at the given wavelength at a second angle relative to vertical. The stagger-tuning of the first grating section and the second grating section results in the light at the given wavelength being scattered at a desired angle the same or near an angle at which an optical fiber is offset from vertical.

  • Publication number: 20200409001
    Abstract: A Dense Wavelength Division Multiplexing (DWDM) photonic integration circuit (PIC) that implements a DWDM system, such as a transceiver, is described. The DWDM PIC architecture includes photonic devices fully integrating on a single manufacturing platform. The DWDM PIC has a multi-wavelength optical laser, a quantum dot (QD) laser with integrated heterogeneous metal oxide semiconductor (H-MOS) capacitor, integrated on-chip. The multi-wavelength optical laser can be a symmetric comb laser that generates two equal outputs of multi-wavelength light. Alternatively, the DWDM PIC can be designed to interface with a stand-alone multi-wavelength optical laser that is off-chip. In some implementations, the DWDM PIC integrates multiple optimally designed photonic devices, such as a silicon geranium (SiGe) avalanche photodetector (APD), an athermal H-MOS wavelength splitter, a QD photodetector, and a heterogenous grating coupler.

  • Publication number: 20200358248
    Abstract: Narrow-optical linewidth laser generation devices and methods for generating a narrow-optical linewidth laser beam are provided. One narrow-optical linewidth laser generation devie includes a single-wavelength mirror or multiwavelength mirror (for comb lasers) formed from one or more optical ring resonators coupled with an optical splitter. The optical splitter may in turn be coupled with a quantum dot optical amplifier (QDOA), itself coupled with a phase-tuner. The phase tuner may be further coupled with a broadband mirror. The narrow-optical linewidth laser beam is generated by using a long laser cavity and additionally by using an integrated optical feedback.

  • Patent number: 10805004
    Abstract: Examples described herein relate to reducing a magnitude of a supply voltage for a circuit element of an optical transmitter device. In some such examples, the circuit element is a driving element that is to receive a first electrical data signal and to provide a second electrical data signal to an optical element that is to provide an optical data signal. A testing element is to compare the optical data signal to the first electrical data signal to determine whether the optical transmitter device meets a performance threshold. When the device meets the performance threshold, a regulating element is to reduce a magnitude of the supply voltage of the driving element.

  • Patent number: 10795104
    Abstract: A photonic integrated circuit package includes two arrays or sets of integrated comb laser modules that are bonded to a silicon interposer. Each comb laser of an array has a common or overlapping spectral range, with each laser in the array being optically coupled to a local optical bus. The effective spectral range of the lasers in each array are different, or distinct, as to each array. An optical coupler is disposed within the silicon interposer and is optically coupled to each of the local optical buses. An ASIC (application specific integrated circuit) is bonded to the silicon interposer and provides control and operation of the comb laser modules.
