Abstract

Optimal demodulation of differential phase-shift keying signals at 10Gbits is experimentally demonstrated using a specially designed structured fiber Bragg grating composed by Fabry–Perot coupled cavities. Bit-error-rate measurements show that, as compared with a conventional Gaussian-shaped filter, our demodulator gives 2.8dB performance improvement.
