Chirp grating
WebGrating Period Chirp is the distance-dependent grating period modulation. The default Period Chirp options are listed below, where the constant chirp term is the grating period in the middle of the grating, L is the grating length, and the symbol delta (Δ) stands for the total chirp. No chirp (constant period): Linear: Quadratic: Square root: WebThe T70 is Chirped Fiber Bragg Grating (FBG) is available in a wide range of optical specifications. It is produced by axially varying either the period of the grating or the …
