ABSTRACT:
Provided is a wideband ASE light source, which has a high output and a little ripples in a wide band and the output of which is stable. In a wideband ASE light source constructed of a pumping light source that generates a pumping light, an erbium-doped optical fiber that generates an ASE light by incident pumping light, a reflector that is arranged at one terminal portion of the erbium-doped optical fiber and reflects the ASE light radiated from the erbium-doped optical fiber, an optical multiplexer that is arranged between a terminal portion of the erbium-doped optical fiber and the pumping light and optically multiplexes and demultiplexes the pumping light with or from the ASE light and an optical isolator that is arranged between the third terminal portion of the optical multiplexer and an output terminal and removes a return light to the erbium-doped optical fiber, the optical multiplexer has a maximum value of isolation in a wavelength band of 1570 nm to 1600 nm.
