Abstract
A double-cavity fiber Fabry-Perot tunable filter is proposed and experimentally demonstrated. There are two cavities in the tunable filter. The two cavities have close properties, and are driven by same piezoelectric transducers. One cavity is used to scan wavelength, and another one is used to calibrate the wavelength. The double-cavity filter is anticipated to be used to interrogate not only the spectra of passive components, but also that of active light sources.
