ABSTRACT:
SC light is generated from the input signal2, of an OTDM signal light1with wavelength λs1and an input signal2with wavelength λs2using an optical fiber and the like, and the wavelength of the SC light is converted into wavelength λs1using a BPF with center wavelength λs1(a specific-timing optical pulse with wavelength λs1is extracted from the SC light). After the addition timing of the wavelength-converted light is adjusted by a delayer (τ) both this wavelength-converted light and signal light1are inputted to an optical add circuit and are added.
