摘要
An optical device for dynamic gain adjusting includes a dynamic gain adjusting filter having one or more semiconductor optical amplifiers. The dynamic gain adjusting filter may allow dynamically-adjustable spectral gain characteristics. A dynamic gain adjusting filter may be part of an amplifier module or other optical device module, or as an optical module itself. The dynamic gain adjusting filter may be used to reduce gain ripple, control gain tilt, and/or compensate for other gain variations. The one or more semiconductor optical amplifiers of the dynamic gain adjusting filter may be designed and/or controlled to produce different gain profiles. For example, the active region of the semiconductor optical device may comprise several subregions having different structures, dimensions, and/or doping characteristics.
