Abstract
In this paper, we introduce our recent developments in the design techniques for high channel-count fiber Bragg gratings (FBG). Based on a double sampling method, we theoretically demonstrate a linearly chirped FBG with channels up to 153, which could be used as the dispersion compensator. Moreover, we propose a novel technique for the realization of a multi-channel notch filter by using a thermally-induced phase-shift of this kind of FBG. As an example, a multi-channel narrow band-pass filter is realized and successfully used to implement a multi-wavelength fiber laser.
