Dual-pump driven, dispersion-synthesized parametric mixers have been identified as an efficient means for wavelength multicasting. In particular, four-mode phase-sensitive (PS) architecture, seeded by frequency-locked and phase-correlated four input optical signals, allows the parametric multicasting operated with ultralow noise and regenerative properties. To further corroborate the superiorities...
We demonstrate the first high-count signal replication accompanied with phase-and-amplitude-noise-squeezing in a four-mode phase-sensitive process. Errorless detection of the phase-modulated information on a 5.8-GHz-phase-noise broadened carrier has been accomplished over 20-copies in a parametric multicaster.
Amplitude-noise squeezing due to saturation in parametric multicasting is investigated. The improved receiver sensitivity of 10 copies by 2-dB over a phase-insensitive device has been obtained as a result of signal-gain elevation, and noise-quenching in a four-mode phase-sensitive parametric multicaster.
An ultra-low loss and high conversion efficiency silicon waveguide is used as sampling gate via four waves mixing, and 5.2 effective number of bits of signal at 40-GHz is achieved by 2-GHz cavity-less pulse source.
The principle, implementation scheme and recent experimental progress of low noise optical frequency multicasting are reviewed, relying on four-mode phase-sensitive process in fiber-based parametric mixer with normal dispersion.
