| 英文摘要 | An objective of the present invention is to provide a semiconductor optical amplifier (SOA) device, and a method of operating the SOA device. semiconductor optical amplifier (SOA) device, comprising: a semiconductor optical amplifier having a semiconductor substrate with an optical amplifier waveguide therein and a sequence of drive electrodes being located over a surface of aforesaid semiconductor substrate, aforesaid sequence extending along a light propagation direction in aforesaid optical amplifier waveguide; a light detector connected to measure a power of signal light input to aforesaid semiconductor optical amplifier; an electronic controller configured to inject currents into said sequence of drive electrodes based on aforesaid power measurement by the light detector. Compared with the prior art of an SOA device generally having one driving electrode, the present invention has the following advantages: by adjusting the magnitudes of currents injected into respective driving electrodes of the semiconductor optical amplifier, the solution of the present invention can increase the linear amplification region, thereby performing error-free signal amplification within a greater reception power range, which further avoids distortion of signal transmission. |
