Multi-wavelength transmitter

Abstract

Various aspects of multiple-channel light transmitting systems are disclosed. The system may include a multiple-wave length light source, a demultiplexer; a modulator, and a wavelocker. The wavelocker is configured to drive the light source such that said multiple wavelengths coincide with the ITU grid. The system may also include other elements including a locker or a mode-locking servo, where the servo is configured to adjust the mode locking method frequency to coincide with the spacing of the ITU grid. Further additional elements may include an optical amplifier or an equalizer. The equalizer may include a filter whose transmission function varies with wavelength.
