Abstract: An optical transmitter comprises an array of modulated sources having different operating wavelengths approximating a standardized wavelength grid and providing signal outputs of different wavelengths. Signal outputs of the modulated sources are optically coupled to inputs of the wavelength selective combiner to produce a combined signal output from the combiner. The wavelength selective combiner has a wavelength grid passband response approximating the wavelength grid of the standardized wavelength grid. A first wavelength tuning element is coupled to each of the modulated sources and a second wavelength tuning element is coupled to the wavelength selective combiner. A wavelength monitoring unit is coupled to receive a sampled portion the combined signal output from the wavelength selective combiner. A wavelength control system is coupled to the first and second wavelength tuning elements and to the wavelength monitoring unit to receive the sampled portion of the combined signal output. The wavelength control system adjusts the respective wavelengths of operation of the modulated sources to approximate the standardized wavelength grid and for adjusting the optical combiner wavelength grid passband response to approximate the standardized wavelength grid.

Abstract: A method of tuning optical components integrated on a monolithic semiconductor chip having a plurality of first optical components integrated on the chip with each fabricated to approximate an emission wavelength along a given wavelength grid and together forming a first optical component wavelength grid. A second optical component is integrated on the chip with and optically coupled to the group of first optical components. The second optical component has a second optical component wavelength grid approximating the given wavelength grid where at least one emission peak along the second optical component wavelength grid is within an acceptable wavelength tolerance range of a particular first optical component of the first optical component wavelength grid but not the same as a corresponding emission wavelength of a particular first optical component. The method involves, among other approaches, the tuning a corresponding emission wavelength of the particular first optical component to have a wavelength response approximating the at least one emission peak of the second optical component wavelength grid.

Abstract: Photonic integrated circuits (PICs), also referred to as opto-electronic integrated circuits (OEICs), and more particularly to a PIC in the form of an optical receiver PIC or RxPIC chip and an optical transmitter PIC (TxPIC) are employed in an optical transport network. Integrated on the RxPIC chip, starting at the input end which is coupled to receive multiplexed optical data signals from an optical transport network is an optical amplifier, an optical demultiplexer, and a plurality of on-chip photodiodes (PDs) each to receive a demultiplexed data signal from the AWG DEMUX for optical-to-electrical signal conversion. The optical input amplifier may be an on-chip gain clamped semiconductor optical amplifier (GC-SOA) or an off-chip fiber amplifier. The optical input amplifier may be optional if the channel signal demultiplexer provides for minimal insertion loss which is optimum with a properly designed arrayed waveguide grating (AWG) demultiplexer.

Abstract: A FEC enhanced system for an optical transport or communication network that includes an optical transmitter that has a transmitter photonic integrated circuit (TxPIC) chip having an integrated circuit comprising an array of modulated sources providing a plurality of optical modulated channel signals comprising digital bit data streams where each signal is at a wavelength on a wavelength grid. The modulated channel signal outputs from the modulated sources are provided to an integrated multiplexer in the circuit to provide a WDM output signal at a circuit output. At least one FEC encoder is coupled to the modulated sources to encode error-correcting code containing redundant information of the data bit stream for each channel signal. An optical receiver in the network includes a receiver photonic integrated circuit (RxPIC) chip having an integrated circuit comprising an input to a demultiplexer and an array of photodetectors coupled to outputs of the demultiplexer. At least one FEC decoder is coupled to the photodetectors to provide decoded data relating to the bit error rate (BER). Information relating to the BER is provided by a controller at the optical receiver to provide real-time information to the optical transmitter relating to optical characteristics of the modulated sources based upon the BER data.
