Synchronous optical signal generating method and optical signal generator synchronization

摘要

An optical phase detector means for generating a phase error signal comparing the phase of the beat light signal, a shaping means for shaping the phase error signal and the reference light signal and generate an optical beat signal based on the phase error signal that is the shaped and outputs by, and a voltage controlled optical signal generating means is fed back to the phase detector means the optical beat signal, the voltage controlled optical signal generating means, the electrical signal corresponding to the phase error signal that is the shaped an optical comb generator for generating a voltage controlled electrical signal generating means generates and outputs the optical comb signal with an optical spectrum lines of the frequency intervals corresponding to the electrical signal generated by the voltage controlled electrical signal generating means, 2 mode selecting means for selecting an optical signal of the optical spectral lines having two different wavelengths from the optical comb signal, and outputs as multiplexes optical beat signal the optical signal of the two wavelengths is the selected, the optical beat signal an optical signal generating device synchronization is characterized by comprising a multiplexing means 2 mode which is fed back to the phase detector means.
