Abstract :
We demonstrate simultaneous balanced DPSK demodulation of 40 Gb/s WDM channels using a single periodic sampled fiber-Bragg-grating. The reflection (transmission) spectrum serves as the constructive (destructive) port of a traditional delay-line-interferometer. We observe approximately 0.5 dB required OSNR variation across the band of the FBG.
