π-phase-shifted FBG
Description
Datasheet

Phase shifted FBGs have a very narrow peak within its transmission/reflection spectrum. Phase shifted FBG is a grating with phase defect in the center. While the grating length determines its bandwidth, spectral width of that peak depends on the strength both parts of FBG. Typical FWHM has a value 0.1nm – 0.005 nm.
