Abstract Microwave photonic filters have been regarded as an alternative to traditional radio‐frequency because of their wide bandwidth and large tunability. Integrated microwave can integrate all necessary components into a single chip are highly demanded for future applications. Here, integrated frequency‐tunable bandpass filter based on silicon platform is proposed demonstrated. The consists...
We demonstrate pulsewidth-stretchable Er-doped femtosecond mode-locked fiber lasers by incorporating a tunable short-pass edge filter into the ring cavity. Pulsewidth stretch ratio of 3.53 (882/250) can be efficiently achieved under a temperature variation of 4oC.
A design approach for a tunable active filter of constant bandwidth and center-frequency gain is described. The approach is based on a feedback configuration with a complex pole pair in the forward transfer function, and a complex zero pair in the feedback transfer function. Center frequency tuning is achieved with the variation of only one element, a potentiomenter, which controls the feedback...
