SEMICONDUCTOR OPTICAL AMPLIFIER |
摘要 |
PROBLEM TO BE SOLVED: To provide a semiconductor optical amplifier capable of suppressing gain variations due to input luminous intensity without causing oscillation light mixed in the guide direction of signal light. SOLUTION: Stimulation is caused in a direction orthogonal to the guide direction of the signal light by embedding n-GaInAsP current block layers 504 to both sides of a GaInAsP active layer 502 formed on an n-InP substrate 501 and forming n-InP embedded layers 510 arranged in a direction orthogonal to the GaInAsP active layers 502 at a prescribed interval to the n-GaInAsP current block layers 504.
