  • Patent number: 11036014
    Abstract: Improved systems and methods are provided to implement coherent communication. The system includes an interposer to route the components of an integrated photonic circuit. The interposer provides an interface to couple the components of the integrated photonic circuit including an optical source, modulator, coherent transmitter, coherent receiver, and interconnects therebetween. The optical source can be a grating-coupled surface-emitting laser (GCSEL). The GCSEL splits an optical signal into two symmetrical optical signals that are directed by a waveguide to a coherent transmitter and/or a coherent receiver of the integrated photonic circuit. Coherent communication is maintained and the need for a second laser in the coherent receiver is avoided through the structure of the GCSEL granting dual functional to the optical source.

  • 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.
