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.

Abstract: A photonic integrated circuit (PIC) includes a semiconductor substrate with a main bus waveguide disposed within the substrate. Two or more ring lasers are disposed within the substrate and are optically coupled to the main bus waveguide. The ring lasers have a wavelength control mechanism allowing change of a lasers emitted wavelength. A wavelength selective filter is optically coupled to the bus waveguide. A control circuit is electronically coupled to each wavelength control mechanism, and the wavelength selective filter. The control circuit in conjunction with the selective filter allows monitoring of a ring laser's wavelength on the main bus waveguide. Based on a determined wavelength, the control circuit may change a ring laser wavelength to a desired wavelength to achieve a desired wavelength spacing for each of the ring lasers. The PIC may be integrated as a coarse wave-length division multiplexing (CWDM) transmit module.

Abstract: One embodiment provides an optical encoder. The optical encoder includes an optical comb source to generate a multi-wavelength optical signal; a number of optical filters sequentially coupled to the optical comb source, with a respective optical filter being tunable to pass or block a particular wavelength of the multi-wavelength optical signal based on a corresponding bit value of a multi-bit search word; and a common output for the optical filters to output the filtered multi-wavelength optical signal, which encodes the multi-bit search word and can be used as an optical search signal for searching an optical content-addressable memory (CAM).

Abstract: A fiber loop includes a plurality of processors coupled to each other and a controller coupled to each of the plurality of processors. The controller is configured to: assign to each of the plurality of processors a number of wavelengths for interconnect communications between the plurality of processors; receive, from a first processor of the plurality of processors, a request for one or more additional wavelengths; determine whether an interconnect bandwidth utilization on the fiber loop is less than a threshold; and in response to determining that the interconnect bandwidth utilization on the fiber loop is less than the threshold, reassign, to the first processor, one or more wavelengths that are assigned to a second processor of the plurality of processors.

Abstract: An optical transceiver module includes an optical transceiver and a controller. The optical transceiver has a ring filter configured to transmit optical signals from or receive optical signals for the optical transceiver module. The controller is configured to: detect a carrier frequency at the optical transceiver; detect a data signal frequency of data at the optical transceiver; determine a bit error rate of the data; and in response to determining that the bit error rate of the data is greater than a threshold, periodically vary a central wavelength of the ring filter at a frequency at least three orders slower than the data signal frequency.

Abstract: In the examples provided herein, a system has a first racetrack resonant waveguide structure, positioned to enable an input light signal to couple from a first waveguide; and a second racetrack resonant waveguide structure, positioned to enable the input light signal to couple between the first racetrack resonant waveguide structure and the second racetrack resonant waveguide structure, and further positioned to enable an output light signal to couple from the second racetrack resonant waveguide structure to a second waveguide. The system also has a primary heating unit, positioned to heat a primary region including a first portion of the first racetrack resonant waveguide structure and a first portion of the second racetrack resonant waveguide structure, to change a central frequency and a passband width for the system.

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.
