Title:
BROADBAND LIGHT SOURCE USING SEMICONDUCTOR OPTICAL AMPLIFIER
Document Type and Number:
Japanese Patent JP2005123612
Kind Code:
A
Abstract:
To provide a broadband light source that maintains low gain ripples, without reducing the reflective index at an output end, even in a semiconductor optical amplifier having high gain.
The light source has an active layer 511 as a gain region; a lower clad layer 512 and an upper clad layer 513; a semiconductor optical amplifier 510, having a nonreflective layer 515 formed both ends of the active layer 511 for amplifying an input optical-signal; and a reflector 530, which is disposed outside the semiconductor optical amplifier 510 and allows light output from the semiconductor optical amplifier 510 to be reflected and input again into the active layer 511, thereby minimizing the gain ripples of the semiconductor optical amplifier 510.
