摘要： An optical transmitter comprises a monolithic transmitter photonic integrated circuit (TxPIC) chip that includes an array of modulated sources formed on the PIC chip and having different operating wavelengths approximating a standardized wavelength grid and providing signal outputs of different wavelengths. A wavelength selective combiner is formed on the PIC chip having a wavelength grid passband response approximating the wavelength grid of the standardized wavelength grid. The signal outputs of the modulated sources optically coupled to inputs of the wavelength selective combiner to produce a combined signal output from the combiner. A first wavelength tuning element coupled to each of the modulated sources and a second wavelength tuning element coupled to the wavelength selective combiner. A wavelength monitoring unit is coupled to the wavelength selective combiner to sample the combined signal output. A wavelength control system coupled to the first and second wavelength tuning elements and to said wavelength monitoring unit to receive the sampled combined signal output. The wavelength control system adjusts the respective wavelengths of operation of the modulated sources to approximate or to be chirped to the standardized wavelength grid and for adjusting the optical combiner wavelength grid passband response to approximate the standardized wavelength grid.

摘要： Embodiments of the present invention analyze a plurality of parallel channels and identify specific channel(s) that have skew outside of an acceptable skew error margin. In certain embodiments, this skew is identified by determining the timing misalignment between a channel under test and a deskew channel. Other channels within the plurality of channels are masked by transmitting a repeating masked bit pattern. This timing misalignment may be measured by comparing a segment within the channel under test to a corresponding segment within the deskew channel and identifying a time differential between the two segments.

摘要： The present invention provides a system, apparatus and method to compute a route through a network having both digital nodes and optical express-thru nodes. According to various embodiments of the invention, a network topology is generated in which both digital nodes, optical express-thru nodes, and optical nodes are identified, and both physical and virtual links between these nodes are mapped. The network connectivity is identified, at least in part, by broadcasting a local link state advertisement and optical carrier group binding information to neighboring nodes, which enables both physical and virtual neighboring nodes to be identified. Once a topology is generated, both physical and virtual link characteristics are analyzed to ensure link diversity for traffic through the network and load balancing functionality across the network.

摘要： A wavelength independent multi-section optical coupler having at least three optical couplers, and at least two differential phase cells. Each optical coupler has two waveguides forming a coupling region having a net coupling value. The coupling value for each coupling region of the at least three optical couplers is different than the coupling values of the other two coupling regions. Each differential phase cell connects adjacent ones of said optical couplers. Each differential phase cell causes a differential phase shift in light signals traversing between the optical couplers, wherein the differential phase shifts of the differential phase cells, and the coupling value for each coupling region are chosen so as to minimize wavelength, and fabrication sensitivity of said wavelength independent multi-section optical coupler for a designed power splitting ratio.

摘要： A system, apparatus and method are described for controlling the gain across one or more amplifier nodes within an optical span. In one embodiment, a fast local amplifier constant gain control loop is provided that maintains a constant gain across an amplifier node for each of the channels within an optical signal. A slow link level gain setting control loop is provided to set and/or adjust the target gain on the amplifier node(s). A gain adjust sequence is performed by the slow link level gain setting control loop to adjust the target gain(s) in response to various events and mechanisms. A 'time of flight' protection method is also provided to ensure consistency between the fast local amplifier gain control loop and the slow link level gain setting control loop.

摘要： Consistent with the present disclosure, a transceiver is implemented as a photonic integrated circuit (PIC) that includes a transmitter and a receiver. A laser is also provided that provides light to a splitter, which supplies a first portion of the light to the transmitter and a second power of the light to the receiver. Semiconductor optical amplifiers (SOAs) are provided at one or more locations on the PIC. In one example, at least one SOA is provided in the transmitter so that the transmitted optical signal has a desired power, and at least another SOA is provided in the receiver so that the local oscillator signal has a desired power. In a further example, an SOA is provided in the receiver to boost the power of the received optical signal. Preferably, the transceiver, including the SOAs, is monolithically integrated on a substrate, such as a substrate including indium phosphide (InP). Moreover, the SOA can be readily controlled via a low voltage current source consuming minimal electrical power.
