Spectrally matched modulation of radiation of injection laser in traveling-wave amplifier below 2 GHz
Abstract
An AlGaAs laser is modulated by modulating the pumping current of a traveling wave amplifier. The experimental setup employs a single-frequency laser with an external dispersion resonator as a master oscillator. The optical spectrum width did not exceed twice the frequency of the modulating signal. Spectrally matched modulation minimizes the dispersion spreading of the light pulse, and implements special multiplexing of optical communications channels practically up to the theoretical limit.
