Abstract

Eye-pattern diagrams confirmed a negative feedback effect was generated by the band pass filter in the module. The negative feedback effect is able to recover signal loss to a far higher definition and a much lower error probability. The modulation degree ratios of the module with negative feedback also appeared to have optical characteristics of a higher fidelity and a more stable baseline. All of our results confirmed the fact that the module induces a negative feedback response. The all-optical triode equipped with the module was functional at a control power range of 0.01 to 1 mW.
