摘要： An apparatus includes a non-solitonic all-optical communication path having serially connected first and second segments. The first segment end-couples to a lumped optical transmitter. The second segment end-couples to a lumped optical receiver. Each segment has a series of spans of transmission optical fibers. The all-optical communication path has an optical phase conjugator that optically end-couples the first segment to the second segment. The optical phase conjugator is positioned away from the path's midpoint.

摘要： A process optically transports digital data over an all-optical long-haul communication path. The process includes transporting digital optical data signals at a selected bit rate and a selected wavelength over a sequence of transmission spans. The sequence includes 70 percent or more of the spans of the long-haul all-optical communication path. Each span of the sequence has a primary local maximum optical power point for the wavelength on a transmission fiber and nearest to an input of the span. The transporting causes a cumulative dispersion of each signal to evolve such that residual dispersions per span are positive over some of the spans and are negative over other of the spans. At the primary local maximum power points, magnitudes of cumulative dispersions of the signals in pico seconds per nanometer remain at less than 32,000 times the inverse of the bit rate in giga bits per second.

摘要： The desirable effects of an optical phase conjugator are accompanied by a frequency shift with reversal of the frequency order of channels in a multichannel optical communication system. Such effects are rectifiable by employing a sequence involving demultiplexing the multichannel signal, operating on the individual, demultiplexed channel with a corresponding optical phase conjugator or frequency shifter followed by multiplexing the signal. This sequence is combined with a complementary operation—optical phase conjugator to complement a frequency shifting sequence or frequency shifting to complement an optical phase conjugating sequence.

摘要： An optical fiber transmission system includes a series of optical fiber transmission spans and one or more all-optical signal processors. The optical fiber transmission spans are connected to form an optical communication path. Each all-optical signal processor directly connects a corresponding adjacent pair of the spans. Each all-optical signal processor includes an optical wavelength converter having input and output ports and a dispersion adjustment module connected to the input port of the optical wavelength converter of the same processor. The dispersion module is also configured to adjust cumulative dispersions of some received optical pulses to be outside of a range for the cumulative dispersions of corresponding optical pulses in the span directly preceding the same processor.

摘要： An apparatus includes an optical wavelength-converter and a polarization splitter. The polarization splitter is configured to receive input and pump light, to direct a first polarization component of the received input and pump light to a first optical path, and to direct a second polarization component of the received input and pump light to a separate second optical path. The optical wavelength-converter has first and second optical ports. The first optical port is at an end of the first optical path. The second port is at an end of the second optical path. The wavelength-converter outputs wavelength-converted light from one of the ports in response to receiving the input and pump light at the other of the ports. The two optical paths may include polarization-maintaining optical waveguides. The polarization splitter and optical paths may be configured to transmit substantially the same pump light intensity to the two optical ports.
