Fiber Bragg grating chirp
The most common type is the linear chirped grating, where the period of the grating varies according to a linear law. Such gratings are recorded with the help of special phase masks with a variable period. The method employs multistage pairs of circulators and tanh-apodized fiber Bragg gratings with. Researchers experimentally demonstrate flexible and customizable filtering of broadband optical signals using chirped and tilted fiber Bragg grating technique While fiber Bragg grating is widely used for selectively filtering wavelengths during optical transmission, existing techniques are.
