ABSTRACT:
A tunable wavelength converter generates a selectable wavelength for an optical signal. The tunable wavelength converter includes an input active section, an output active section, an interferometer and an optical wavelength selector. The above components are integrated on a substrate between two mirrors. An optical input signal at a first wavelength is input through the input active section which in conjunction with the output section and the interferometer controls the amplitude of an optical signal at a second wavelength propagating in the laser cavity. The information contained in the amplitude of the input signal is transferred to the optical signal in the interferomic laser cavity and output by the output active section. Thus, the information of the optical input signal at the first wavelength is transferred to the optical output signal at the second wavelength.
