摘要
An impulse response method and Fourier transformation are proposed to theoretically analyze the dynamic characteristics of a tunable FFP filter. And the dynamic optical spectrum and time domain characteristics of a FFP tunable filter modulated by an alternating current (AC) dithering signal are derived. The simulated and experimental results show that the method can determine the relation between the AC signal parameters and the dynamic response through either the output optical signal or the output electrical signal. Our experimental results also reveal the dependence of the locking stability of a FFP tunable filter on the amplitude of a dithering signal.
