We fabricated a very narrow-band 0.03-nm (5-GHz) phase-shifted Bragg grating filter at 1290 nm on an LD-3 polymer ridge waveguide. The grating was post processed onto the waveguide by photobleaching using a 457-nm argon ion laser with a phase mask. We present the details of the fabrication process and a measurement of the filter spectrum with an analysis.
