Patent ID: 6876818

Claim:
A system for transmitting signals over an optical fiber using spectrally enriched optical pulses comprising: an optical transmitter with an optical source for generating data modulated spectrally enriched optical pulses having a spectrum substantially wider than a spectrum of Fourier-transform limited pulses of the same duration; said optical transmitter including a clock generator connected to said directly modulated diode laser for providing said spectrally enriched optical pulses with said frequency chirp; and a data modulator connected to an output of said directly modulated diode laser for modulating externally said optical pulses; a data generator connected to said data modulator for driving said data modulator; and a phase shifter connected to said directly modulated laser for providing time delay adjustment between said clock generator and said data generator, the optical fiber coupled to said optical transmitter for propagating said optical pulses throughout the spectrum of said optical pulses being shrinked while propagating along the optical fiber, and an optical receiver within the optical fiber at or beyond an error free propagation distance from said optical transmitter for receiving said optical pulses.
