Abstract
We demonstrate a simple way to fabricate phase-shifted fiber Bragg grating in polymer optical fibers as a narrowband transmission filter for a variety of applications at telecom wavelengths. The filters have been fabricated by overlapping two uniform fiber Bragg gratings with slightly different periods to create a Moiré grating with only two pulses (one pulse is 15â¯ns) of UV power. Experimental characterization of the filter is provided under different conditions where the strain and temperature sensitivities were measured.
