Abstract

Ultrashort laser pulses with durations in the picosecond and femtosecond range offer tremendous potential for applications to ultrahigh bandwidth fiber optic communication systems. To realize this potential, however, it is necessary to devise methods for utilizing the ultrahigh bandwidth associated with ultrashort pulses without requiring modulators and receivers to operate at terahertz rates. One solution to this problem is to utilize parallel modulation in the frequency domain to reshape the ultrashort pulse into complex waveforms with very high effective serial modulation rates.
