Abstract
AbstractIn this paper, we present preliminary simulation results of an improved dual grating-assisted fiber filter. As choosing optimum length the total loss is reduced, and coupling efficiency significantly increased compared to the previously reported results. The coupling efficiency is near 100 % range for a desired bandwidth. Dependence of the coupler on period has also been investigated.
