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.
