Abstract: A method and apparatus for modifying the extinction ratio of a modulated optical signal by adapting a modulator driver signal in response to differences in spectral regions of the modulated optical signal. In another embodiment for modifying the extinction ratio of a modulated optical signal, a modulator signal is adapted in response to differences between a profile of the modulated optical signal and a desired profile.

Abstract: A method and system for increasing the capacity and spectral efficiency of optical transmission includes pre-filtering optical pulses utilizing a bandwidth substantially proportional to the bit rate of the transmission system prior to propagating the optical pulses along a transmission fiber and post-filtering the propagated optical pulses utilizing a bandwidth substantially proportional to the bit rate of the transmission system.
