Abstract: A method for per-span optical fiber nonlinearity compensation comprises determining values of fiber parameters characterizing one or more target optical fibers in one or more respective spans of a link, and applying selected weight values to one or more photonic computing chips (PCCs), each PCC integrated in a different respective span of the link, wherein selection of the weight values is based on the values of the fiber parameters and a mapping associated with each PCC. The method further comprises transmitting an optical signal through the link, wherein each integrated PCC emulates an inverse of a nonlinear transfer function of the target optical fiber in the respective span, thereby reducing nonlinearity contributed by the one or more target optical fibers to the optical signal.

Abstract: In optical signal transmission, an input optical signal is received that has double side band (DSB) spectral characteristics. The input optical signal is optically filtered to produce an output optical signal having single side band (SSB) spectral characteristics. The output optical signal is caused to include a soliton pulse. In optical signal transmission, a modulated RZ optical signal is formed from an input optical signal. The modulated RZ optical signal has single side band (SSB) spectral characteristics. A data modulated optical signal is formed from the modulated RZ optical signal. The data modulated optical signal includes a soliton optical signal that has SSB spectral characteristics and that includes a soliton pulse. The peak power and the mid-amplitude width of the soliton pulse are linked by a relationship that depends on the characteristics of an optical medium in which the soliton pulse travels.
