摘要： A bidirectional optical space transmission system is made up of a pair of optical transmission apparatus. Each optical transmission apparatus comprises a signal generating circuit for generating a pilot signal, a multiplexing section for multiplexing the pilot signal and a main signal to be transmitted, an electrooptic converter section for emitting an optical signal on the basis of the signal produced by the multiplexing process, a light receiving element for receiving an optical signal transmitted from the partner optical transmission apparatus and detecting a pilot signal contained therein, and a demodulation circuit for demodulating the pilot signal detected by the light receiving element. Pilot signals multiplexed with main signals to be transmitted through the bidirectional optical transmission system are subjected to spreading modulation and demodulated for spreading by the demodulation circuit.

摘要： A power conservative multi-segment LED transmitter including a multi-segment LED with a plurality of independently addressable LED segments, each LED segment suitable for selectively emitting a beam segment. A controller selectively enables and disables the LED segments. Depending on whether the beam segments overlap or not and whether low or high power is supplied to the enabled LED segments, the combined resulting beam may be a low power steered beam, a power conservative steered beam, an overlapping low power intense steered beam, or an overlapping power conservative steered beam. The steerable multi-segment LED transmitter and receiver system preferably includes an “all enabled” state in which each of the LED segments are enabled and emit a respective beam segment; a “training” state in which the LED segments are selectively enabled and disabled and the receiver determines substantially detected beam segments; and a “steered” state in which only the LED segments emitting the substantially detected beam segments are enabled.

摘要： A system for individually controlling the chromatic dispersion of one or more wavelength division multiplexed (WDM) optical signals, chromatic dispersion is compensated a plurality if individually controllable differential optical delay elements. An example of a suitable differential optical delay element is a tunable fiber Bragg grating filter whose spectral response varies along the length of the grating, i.e. is chirped in a non-linear fashion. The system may, in addition, comprise one or more second individually controllable optical delay elements arranged so as to compensate for any unwanted delays across the wavelength band of a signal introduced by a first delay element. Optical circulators may be used to route signals into and between the pluralities of differential optical delay elements. This system has the advantage of providing a compact multi-channel selective differential delay suitable for compensating for chromatic dispersion in a WDM optical communications network.

摘要： An optical transmission system and method for reducing non-linear distortion caused by the interaction of Self-Phase Modulation and Group Velocity Dispersion is disclosed. An optical link includes a transmitter for providing signals at a first optical wavelength, a transponder for converting the first optical wavelength to a second optical wavelength, a plurality of spans of optical transmission fiber and optical fiber amplifiers, a dispersion compensating device, and a receiver. The system operates at a relatively high input power level. The transponder includes a device for smoothing edges of the rise and fall times of optical pulses, such as an electrical attenuator and low pass filter, so that sharp-edged pulses received from the transmitter are transformed to a Gaussian shape. A dispersion compensating device, such as an optical fiber grating, also helps to improve the bit error rate as a function of receiver sensitivity despite an overall link length less than 600 km.

摘要： A channel selector which selects one or more channels from input multi-channel optical signals for routing to predetermined destinations within an optical communication system is disclosed. The channel selector selects one or more channels by first splitting portions of the input multi-channel optical signals across two or more optical paths. Thereafter, a desired phase response is applied to the split portions of the multi-channel optical signals. The desired phase response is applied to the split portions of the multi-channel optical signals so the channels therein interfere with each other either constructively or destructively when the split portions of the multi-channel optical signals are combined. The channel selector has a structure which includes a plurality of input ports, a plurality of output ports, a splitter, a combiner, one or more all-pass optical filters, and a plurality of optical paths.

摘要： A dispersion compensator provides dispersion compensation to a WDM optical signal having a plurality of channels located at different wavelengths and traveling in an optical transmission path. The dispersion compensator includes an optical splitter adapted to receive the WDM optical signal. The optical splitter has first and second output ports such that a subset of the plurality of channels are directed along the first output port and remaining ones of the plurality of channels are directed along the second output port. A dispersion compensating element is coupled to the first output port and a multiplexing element having a first input port is coupled to second output port of the optical splitter. The multiplexing element also has a second input port coupled to the dispersion compensating element and an output port on which the subset of channels and the remaining ones of the channels are recombined.

摘要： An optical signal receiver for rapid and error free translation of optical signals into electrical signals is disclosed. The receiver is coupled to a light source. The light source is amplified and then split into two segments. One of the segments is delayed by a specific amount of time. Both segments are optically coupled to a photo detector. Each photo detector is coupled in parallel and are connected by two output terminals. When the voltage output by each photo detector is equal, the output terminals are balanced and will not have any voltage. The circuit will provide a voltage output on the terminal only on differential photocurrents sensed by the detector elements. The quiescent magnitude of the voltage output is a function of the value of the reverse bias voltage applied by the two voltage sources.
