摘要： Code-multiplexed communication systems, apparatus, and methods include coders that encode and decode data streams with synchronous, substantially orthogonal codes. Code-multiplexed communications systems encode data signals with such codes to control levels of decoding artifacts such as cross-talk at times or time intervals in which data is recovered. Some systems are based on synchronous, orthogonal codes that are obtained from complex orthogonal vectors. In an example, a three-level temporal-phase code that includes nine code chips and encodes and decodes data signals is a seven-channel communication system.

摘要： Programmable waveguide coders are disclosed that include one or more corrugation segments and one or more spacer segments formed on or in a waveguide defined by a core in an electro-optic substrate. Each of the corrugation segments and the spacer segments are independently controllable with voltages applied to each segment's electrodes. The spacer segments permit application of a phase modulation to an input while the corrugation segments act as tunable gratings, wherein a center grating wavelength is tunable by applying a voltage to an electrode associated with the corrugation segment. In some embodiments, coders include only corrugation segments or only spacer segments. Such coders can be strain tuned or thermally tuned. The coders can be programmatically tuned to code or decode a time-wavelength code or other code.

摘要： A laser system includes a seed laser operable to output a seed laser signal along an optical path and a phase modulator disposed along the optical path and operable to receive the seed laser signal. The laser system also includes a phase modulator driver coupled to the phase modulator. A drive signal from the phase modulator driver is operable to produce, as an output from the phase modulator, an unmodulated seed laser signal when the drive signal is associated with a first state and a modulated seed laser signal when the drive signal is associated with a second state. The laser system further includes a fiber amplifier disposed along the optical path and operable to receive the output of the phase modulator. A spectral bandwidth of an output of the fiber amplifier associated with the second state is less than a spectral bandwidth of the output of the fiber amplifier associated with the first state.

摘要： Optical communication systems include a central station that encodes data transmitted to multiplexing (mux) stations or user stations. The central station also decodes data received from the mux stations or user stations. Encoding and decoding are performed using codes, such as composite codes, that designate sources and destinations for data. The mux stations, user stations, and the central station have address encoders and decoders that use, for example, fiber Bragg gratings to encode or decode optical signals according to a code such as a composite code derived by combining codes from one or more sets of codes. A passive optical network comprises one or more levels of mux stations that use such address decoders and encoders to receive, decode, and encode data for transmission toward a central station or a user station.

摘要： Encoders and decoders for applying composite codes to optical data signals include encoders and decoders for applying both subcodes and supercodes. The subcodes have a duration selected as less than or equal to an interchip duration or a chip duration of the supercodes. The encoders and decoders (“coders”) include fiber Bragg gratings configured to encode or decode a subcode, a supercode, or a composite code. By coding with a subcode coder and a supercode coder, a coder is reconfigurable by selecting different subcodes or supercodes. Communication systems and methods using composite codes are also described.
