Abstract

We have fabricated in-plane slanted gratings on azo-functionalized polymeric films using a fast, direct-writing method. By properly adjusting the resonance, these gratings can be used as 90° integrated reflectors and add/drop filters in the plane of the film. We have produced an attenuation of $14.8\mathrm{dB}$ at $1560.2\mathrm{nm}$ with a FWHM of $6.47\mathrm{nm}$. Also, a signal of $1548\mathrm{nm}$ wavelength was added to the output from a different direction. Any light shifted from the resonance will pass through the filter undisturbed.
