Abstract :
Experimental findings on a novel, compact, low cost tuneable and switchable guided wave optical filter using a composite holographic Bragg grating as the perturbation element of the guided optical field is summarized. The optical transmittance of the filter is measured by an optical spectrum analyzer. The tuning of the filter reflection response is also obtained.
