To provide the wavelength converting element for one-to-many wavelength, which is capable of reducing the limitation by the intensity of saturated light of a semiconductor light amplifier and is capable of increasing the number of convertible wavelengths.
Plural CW lights whose wavelengths are respectively different are bisected in a multiplexer/demultiplexer 21 to be respectively made incident on semiconductor light amplifiers 11, 12 and also a signal light is made incident on one of the semiconductor light amplifier 11 via a multiplexer/demultiplexer 22 and, then, one of the bisected plural CW lights are phase modulated and reflected by a high reflection coating film 13 and are multiplexed in the multiplexer/demultiplexer 21 and, thus, an output light whose intensity is modulated by interference with plural CW lights whose phases are modulated and plural CW lights whose phases are not modulated is emitted from this element.
