ALL-OPTICAL WAVELENGTH CONVERTER CIRCUIT

摘要

A method and apparatus for transferring information of an optical information-bearing signal from a first wavelength to a second wavelength. The method is implemented in an all optical wavelength converter circuit (200) which includes a laser diode (115) in communication with a polarization controller (210). An information bearing signal having a first wavelength is input to the circuit (605). A polarization controller (210) adjusts (620) the polarization of the information bearing signal. The laser diode (115) receives (625) the polarization-adjusted information-bearing signal and generates (630) a converted information bearing signal by transferring the information of the polarization adjusted information-bearing signal from the first wavelength to the second wavelength.
