Parametric amplification and phase preserving amplitude regeneration of a 640 Gbit/s RZ-DPSK signal.
We report the first experimental demonstration of parametric amplification and all-optical phase-preserving amplitude regeneration for a 640 Gbit/s return-to-zero (RZ) differential phase-shift keying (DPSK) optical time division multiplexed (OTDM) signal. In the designed gain-flattened single-pump fiber optical parametric amplifier (FOPA), 620 fs short optical pulses are successfully amplified ...
متن کاملNumerical Simulations of the Long-Haul RZ-DPSK Optical Fibre Transmission System
Return-to-zero differential phase shift keying (RZ-DPSK) is a promising modulation format for the long-haul large capacity optical fibre transmission system, and it demonstrated a superior performance compared to the conventional intensity-modulation direct-detection (IM-DD) system experimentally (Cai et al., 2006; Inoue et al., 2004; Rasmussen et al., 2004). For the IM-DD based long-haul syste...
متن کاملNZDF Using OTDM and RZ-DPSK Format
We demonstrate six-channel 160-Gb/s wavelength-division-multiplexed transmission over 20 100-km spans of nonzero-dispersion fiber, with a spectral efficiency of 0.53 b/s/Hz. We achieve this result using optical-time-division multiplexing with polarization bit interleaving and return-to-zero differential-phase-shift-keying modulation format. We also operate at 170.6 Gb/s per channel to emulate t...
متن کاملSimultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK format conversion in a silicon microring resonator.
Simultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK modulation format conversion in a single silicon microring resonator with free spectral range equal to twice the signal bit rate is experimentally demonstrated for the first time at 41.6 Gb/s. By utilizing an optimized custom-made microring resonator with high coupling coefficient followed by an optical bandpass filter with appropriate band...
متن کاملTime domain add-drop multiplexing for RZ-DPSK OTDM signals.
We show all-optical time domain add-drop multiplexing for a phase modulated OTDM signal for the first time, to our knowledge. The add-drop multiplexer is constructed of a Kerr shutter consisting of a 375 m long highly nonlinear fiber (HNLF), gamma=20 W(-1)km(-1). Successful time domain add-drop multiplexing is shown for 80 Gb/s RZ-DPSK OTDM signals with a 10 Gb/s base rate.
