CHIRPED-PULSE MULTIPLE WAVELENGTH COMMUNICATIONS SYSTEM

摘要

An apparatus and method provides optical multiple wavelength signals using a single optical broadband source to generate many independent optical wavelength channels. An optical transmitter includes a pulse chirping device which separates the frequency components of periodic optical pulses in the time domain forming separate wavelength channels which are separately modulated by a high-speed broadband optical modulator. A receiver includes a passive splitter to separate the individual wavelength channels. The chirpedpulse transmitter can then be conveniently adjusted to provide optimum overlap of wavelength channels with the modulating channel spectra.
