Abstract: A microcontroller can interact with external ASICs using a multi-serial peripheral interface. The ASICs and the microcontroller can be included in an electrical device or an optical-electrical device. The microcontroller can implement the interface to access the registers of the different ASICs in bulk interactions, including a bulk status request, bulk configuration setting, and bulk data reads.

Abstract: A system is configured to determine a first power level of a first signal output from a first modulator, and determine a second power level of a second signal output from a second modulator. The first signal may include a first optical signal associated with a particular polarization orientation, and the second signal may include a second optical signal associated with the particular polarization orientation. The system is configured to determine a relationship between the first power level and the second power level, and to set, based on the relationship between the first power level and the second power level, a reverse bias voltage associated with the first modulator, where the reverse bias voltage may be used to control the first power level of the first signal.

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.

Abstract: In some embodiments, an apparatus includes an optical transceiver that includes a first set of electrical transmitters operatively coupled to a switch. Each electrical transmitter from the first set of electrical transmitters is configured to transmit an electrical signal from a set of electrical signals. In such embodiments, the switch is configured to switch an electrical signal from the set of electrical signals such that the set of electrical signals are transmitted via a second set of electrical transmitters. Each electrical transmitter from the second set of electrical transmitters is operatively coupled to an optical transmitter from a set of optical transmitters. The set of optical transmitters is operatively coupled to an optical multiplexer. In such embodiments, at least one electrical transmitter from the second set of electrical transmitters is associated with a failure within the optical transceiver.

Abstract: In some embodiments, an apparatus includes a first optical transceiver. The first optical transceiver includes a set of optical transmitters, an optical multiplexer operatively coupled to the set of optical transmitters, and a variable optical attenuator operatively coupled to the optical multiplexer. The variable optical attenuator is configured to receive a control signal from a controller of the first optical transceiver and modulate a signal representing control information with an output from the optical multiplexer. The control information is associated with the control signal and for a second optical transceiver operatively coupled to the first optical transceiver.

Abstract: In some embodiments, an apparatus includes an optical transceiver system that includes a set of optical transmitters and a backup optical transmitter. In such embodiments, each optical transmitter from the set of optical transmitter can transmit at a unique wavelength from a set of wavelengths. The backup optical transmitter can transmit at a wavelength from the set of wavelengths when an optical transmitter from the set of optical transmitters associated with that wavelength fails. In other embodiments, an apparatus includes an optical transceiver system that includes a set of optical receivers and a backup optical receiver. The backup optical receiver can receive at a wavelength from the set of wavelengths when an optical receiver from the set of optical receivers associated with that wavelength fails.

CPC classification number: H04B10/6931 , H04B10/691
Abstract: An optical receiver can implement a transimpedance amplifier (TIA) to process received light using a closed loop optical pre-amplification. The optical receiver can use an average input value of the TIA to control an semiconductor optical amplifier (SOA) or pre-amplification as received average signal varies. The optical receiver can include a gain controller for the TIA that can measure the TIA swing to adjust the gain of the SOA to pre-amplify received light in a closed loop control configuration.
