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 with attenuation of and FWHM of for each channel. The separated channels were directed towards the sides at an approximately angle with respect to the input direction.
