1 results about "Cross gain modulation" patented technology

The application belongs to the technical field of optical communication, and discloses an environment-adaptive optical signal wavelength conversion and regeneration system and method; transient power fluctuation characteristics and rate characteristics are obtained by performing feature extraction on input signal light; the thermal environment state of a semiconductor optical amplifier is monitored by using reference light to determine a gain drift amount; the probe light power is dynamically configured based on the gain drift amount and the rate characteristics, and transient fine adjustment is performed on the bias current according to the transient power fluctuation characteristics; the input signal light and the dynamically configured probe light are coupled into the semiconductor optical amplifier, and conversion light is obtained by using cross gain modulation effect; the conversion light is subjected to code distortion evaluation, and pre-emphasis instructions are generated and fed back to the input signal light modulation link. The application realizes automatic compensation under environment change and effectively suppresses code distortion.
