ABSTRACT:
A fiber optic communication system comprising:an optical signal source adapted to produce a binary amplitude modulated signal; andan optical spectrum reshaper adapted to receive the amplitude modulated signal and to change the instantaneous frequency of the signal at its 0-to-1 and 1-to-0 transitions so as to change the instantaneous frequency of the signal so that it is substantially constant across the 1 pulse.A method for transmitting a signal through a fiber, comprising:generating a second signal from the signal, wherein the second signal comprises a intensity profile and an adiabatic frequency profile;generating a third signal from the second signal, wherein the third signal comprises a intensity profile and a flat-topped frequency profile.
