| 英文摘要 | A multi-stage tunable gain optical amplifier device amplifies an optical signal by a gain amount which can be adjusted in one of the stages of the amplifier. The multi-stage amplifier includes at least two optical amplifier stages coupled in series, one of which is a tunable gain amplifier stage. The optical amplifier stages are characterized by a design parameter which varies from stage to stage. In a preferred embodiment, the design parameter includes a noise figure and a saturable power, with both parameters increasing as the optical signal propagates from stage to stage. As a result, the multi-stage tunable gain optical amplifier can achieve better noise performance and higher output power than a single stage optical amplifier with a constant noise figure and saturable power. |
