π-phase-shifted FBG
Description
Datasheet
Phase shifted Fiber Bragg Gratings (FBGs) feature an extremely narrow peak within their transmission and reflection spectra. A phase shifted FBG is a fiber Bragg grating with a phase defect located at its center, which creates unique optical characteristics. The grating length determines the overall bandwidth, while the spectral width of the narrow peak depends on the strength of both parts of the grating.
The typical full width at half maximum (FWHM) for phase shifted FBGs ranges from 0.1 nm to 0.005 nm, making them ideal for high-precision optical systems and narrowband filtering applications.
