Abstract:
1. An optical communications system comprising: a. an optical transmitter that generates a modulated optical signal at an output; b. an optical link having an input that is optically coupled to the output of the optical transmitter, the modulated optical signal propagating through the optical link so that the dispersion of the optical link is imprinted onto an optical spectrum of the modulated optical signal; c. an optical filter that is optically coupled between the output of the optical transmitter and the input of the optical link, the optical filter reducing second-order non-linearities that result in dispersion in the modulated optical signal during transmission through the optical link; d. a demodulator having an input that is optically coupled to an output of the optical link, the demodulating receiving the modulated optical signal propagated through the optical link and filtering at least a portion of the optical spectrum with the imprinted dispersion of the optical link, thereby mitigating effects of dispersion in the modulated optical signal and generating a demodulated optical signal at an output; and e. an optical detector having an input that is optically coupled to the output of the demodulator, the optical detector generating an electrical data signal.
