Technology Description: Filters of the add/drop and notch types are sought in fiber optic communication networks. The proposed development is distinct because of a fiber Bragg grating of low reflectivity and poor wavelength selectivity in a novel configuration in a fiber optic resonating structure to produce a highly wavelength selective device. A grating structure, achieving the same result alone would be difficult to fabricate. This configuration, which uses nothing more then 2x2 coupler and a fiber Bragg grating, is easy to fabricate. This development is applicable in optical fiber communications. The competitive advantages are: (i) Easy to fabricate configuration (ii) Simple and cost effective.
