A new method for designing tunable bandpass filters
Optics ExpressIn this work, a tunable microwave bandpass filter is designed based on a Fabry-Pérot interference (FPI) cavity, which consists of two nonequivalent FSSs. The upper and lower FSS layers are composed of periodic cross-type units of different sizes, thus having two different central frequencies.

Effective strategy for accessing the multi-pulse regime of mode-locked fiber lasers [PDF]
EPJ Web of Conferences, 2023 We unveil a strategy for configuring mode-locked fiber lasers by means of a tunable bandpass filter, which allows multi-pulse structures to be generated without distortions in their intensity profiles, with significantly reduced pumping power levels.
