Abstract
As one of the fiber-based wide-band promising components, high channel-count fiber Bragg grating has recently attracted great interests. In this paper, we introduce our recent developments in the design techniques for the ultra-high channel-count fiber Bragg gratings (FBG). The key technique is based on the utilization of a continuous phase-only sampling, which is the same as the one for the optimization of a phase-only grating in the diffractive optics. With the proposed sampling method, we have theoretically demonstrated a novel doubly sampled FBG with channels up to 405, which could be used as either the dispersion compensator or the comb filter in broad-band wavelength-division multiplexing (WDM) system.
