We demonstrate a novel optical circuit for the simultaneous demodulation and all-optical clock-recovery of 40 Gb/s WDM NRZ-DPSK signals. The circuit is based on an ad-hoc periodic FBG-filter. We report complete characterization in the whole C-band.
We demonstrate an all-optical circuit that simultaneously performs packet-by-packet clock recovery (CR) and data demodulation from 10-Gb/s nonreturn-to-zero differential-phase-shift-keying packets. It includes a novel power equalizer based on a nonlinear self-polarization switch in a semiconductor optical amplifier that enables operations within 15-dB input power level fluctuations. Data demodulation...
We experimentally demonstrate an all-optical circuit performing clock recovery and data demodulation from DPSK packets. The circuit operates with 15 dB input dynamic range and is suitable for photonic integration
