Abstract

We report the design and fabrication of a widely tunable optical bandpass filter based on using two identical long-period gratings formed along a polymer channel waveguide with a section of the waveguide core removed. The peak transmission of the passband of the fabricated filter is 60 % and the bandwidth of the passband is 6   nm . The filter is thermally tunable over the C + L band (1520–1610 nm) for both TE and TM polarizations with a temperature control of 30 ° C .
