| abstract | (57) [Problem] To provide an optical amplifier which is miniaturized and economical with few components. SOLUTION: The signal light multiplexed by a multiplexer 2 enters an EDF 4 together with pumping light from a pumping light source 3, is pumped and amplified by the pumping light, and is emitted from the EDF 4 to enter a second circulator 5. Then, the light exits from the second port, passes through the optical component 6, and then enters the EDF 4 from the second circulator 5 in a direction opposite to the incident direction, and The light passes through F4 again and is output from the third port of the first circulator 1 via the multiplexer 2. |
