PROBLEM TO BE SOLVED: To provide a fixed-gain semiconductor optical amplifier using the Ranman amplification principle which has a relatively high gain characteristic and a relatively low noise figure without using a pumping light source for a Raman amplifier. SOLUTION: This fixed-gain semiconductor...
