Abstract

We have fabricated a two-dimensional photonic crystal that functions as a two-channel add/drop filter on azo-functionalized polymeric films using a fast, direct-writing method. By properly adjusting the resonance, this structure can be used as a multichannel add/drop filter in the plane of the film. Here, we were able to separate two channels at 1555.7 and 1570.7nm with attenuation of 13.1dB and FWHM of 6.7nm for each channel. The separated channels were directed towards the sides at an approximately 90° angle with respect to the input direction.
