TUNABLE PULSE WIDTH GENERATION OF RETURN-TO-ZERO FORMAT FOR SYSTEM OPTIMIZATION

摘要

A method for tunable optical pulse width generation comprises varying chirp of the signal of the pulse and concurrently varying dispersion of the signal. A system for tunable pulse width generation comprises a phase modulator providing the chirp modulation by modulating peak to peak phase of an optical signal and a tunable dispersion element providing the chromatic dispersion to the optical signal. A system for tunable pulse width return to zero optical signal transmission comprises at least one optical signal, a plurality of amplitude modulators for modulating the signal and a tunable pulse width generator comprising a phase modulator providing the chirp modulation and a tunable dispersion element providing the dispersion.
