Abstract :
We demonstrate an all-fiber periodic frequency comb filter based on sampled fiber Bragg gratings that exploits the spectral Talbot effect for tuning the free spectral range. Using a new cascaded grating design, we have successfully eliminated the interchannel phase fluctuations inherent in the previously reported implementations of such filters
