摘要： In one example, an apparatus includes e first beam splitter having a first output and a second output. A first optical waveguide is coupled to the first output, and a second optical waveguide is coupled to the second output. A first tunable phase delay is further coupled to the second optical waveguide and has a third output. A first set of phase modulators is coupled to the first optical waveguide, and a second set of phase modulators is coupled to the third output of the first tunable phase delay. At least one of the first set of phase modulators and the second set of phase modulators includes a phase modulator that is driven to three or more distinct phase states. A second beam splitter has a first input coupled to the first optical waveguide and a second input coupled to the second optical waveguide.

摘要： Processes and apparatuses described herein reduce the manufacturing time, the cost of parts, and the cost of assembly per laser for photonic interconnects incorporated into computing systems. An output side of a laser assembly is placed against an input side of a silicon interposer (SiP) such that each pad in a plurality of pads positioned on the output side of the laser assembly is in contact with a respective solder bump that is also in contact with a corresponding pad positioned on the input side of the SiP. The laser assembly is configured to emit laser light from the output side into an input grating of the SiP. The solder bumps are heated to a liquid phase. Capillary forces of the solder bumps realign the laser assembly and the SiP while the solder bumps are in the liquid phase. The solder bumps are then allowed to cool.

摘要： One example includes a bias-based Mach-Zehnder modulation (MZM) system. The system includes a Mach-Zehnder modulator to receive and split an optical input signal and to provide an intensity-modulated optical output signal based on a high-frequency data signal to modulate a relative phase of the split optical input signal to transmit data and based on a bias voltage to modulate the relative phase of the split optical input signal to tune the Mach-Zehnder modulator. The system also includes a bias feedback controller to compare a detection voltage associated with the intensity-modulated output signal with a reference voltage to measure an extinction ratio associated with an optical power of the intensity-modulated optical output signal and to adjust the bias voltage based on the comparison to substantially maximize the extinction ratio.

摘要： Systems and apparatuses are disclosed for flexible, mating force-managed optical connections using a plurality of optical connectors and ferrule carrier adapters. Each of the plurality of ferrule carriers comprise a plurality of duplex ferrules disposed within ferrule bays of the ferrule carrier. A bracket of the optical connector gangs the plurality of ferrule carriers together. Ferrule carrier adapters are configured to accept a plurality of optical connectors for inline or orthogonal mating. Each ferrule carrier within the optical connectors is independently floated on the bracket, allowing each ferrule carrier to be mated and demated independently of any other ferrule carrier in the optical connector.

摘要： An optical system includes an optical transmitter having optical transmission channels and an optical receiver having optical reception channels. The optical transmission channels are successively tuned to resonant wavelengths at which lowest transmission channel input currents result in transmission channel output current peaks greater than a threshold. The optical reception channels are tuned to the resonant wavelengths after the optical transmission channels are tuned. Each resonant wavelength has the optical reception channel tuned thereto that has a highest reception channel output current peak at a lowest reception channel input current when the optical transmission channel tuned to the resonant wavelength is temporarily detuned.

摘要： 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.
