Abstract

Combined DLP algorithm and sampled theory, super-narrow FBG filter for arbitrary shaping spectrum can be successfully synthesized, and the process of design and fabrication using one uniform mask are demonstrated. A novel method for a single stage illumination to fabricate dc-free apodized sampled FBG is proposed based on the chirp of sample period. Above design and fabrication method are testified by simulation and experiment results, and a super-narrowband triangle shaping FBG filter with 25pm 3dB bandwidth and side lobes suppression beyond 20dB is fabricated.
