ABSTRACT:
An erbium-doped optical fiber for amplifying a light signal 1 is wound to form a plurality of nearly-closed rings 1a that are arranged in a flat expanded configuration. A light-receiving device 4 receives a spontaneous emission light emitted by the entirety of erbium-doped optical fiber 1 and supplies an electric signal corresponding to the received spontaneous emission light. A laser diode 2 supplies a pumping light to the erbium-doped optical fiber 1 to create a population inversion in the erbium-doped optical fiber. An output-control device 3 controls an output of laser diode 2 in response to the electric signal supplied from the light-receiving device 4. The light-receiving device 4 is located so that the light-receiving device can receive the spontaneous emission light emitted from the entirety of the rings 1a.
