Abstract

We have proposed a new phase-controlled distributed feedback wavelength tunable optical filter with distributed coupling coefficient. The analysis, which is based on the transfer matrix method, reveals that an almost constant peak transmissivity (gain) of more than 37dB, tuning range of better than 21.7Å and side-mode suppression ratio (SMSR) of more than 17dB can be achieved using this structure.
