Abstract
In this paper theoretical research on harmonic response of apodized fiber Bragg gratings written using apodized phase and amplitude masks are presented. Two apodization techniques, namely variable phase step and variable fill factor are employed, and their influence on gratings' reflection efficiency of Bragg wavelength and its harmonic is extensively analyzed. Results show that using an appropriate apodization technique and profile power spectra of apodized fiber Bragg gratings can be widely tailored.
