Detailed characterization of afiber-optic parametric amplifier in phase-sensitive and phase-insensitive operation.

Study of Phase Sensitive Amplifier (psa) Characteristic for 80 Gbit/s Dpsk Data Input Signal

Simulation of phase sensitive amplifier (PSA) of differential phase shift keying (DPSK) data signal in dual pump is presented. The PSA is designed and simulated using OptiSystem software. A dual pump PSA based on cascaded fiber optic parametric amplifier (FOPA) of 80Gbit/s DPSK data signal is investigated in detail on its gain and noise figure. Results show that PSA has higher gain and lower no...

Noiseless phase quadrature amplification via electro-optic feed-forward

The transmission of small optical signals carried by coherent light is fraught with difficulty. Attenuation of the optical power causes degradation of the signal-to-noise ratio as the signal recedes into the quantum noise of the beam. A simple method to rectify this problem would be to amplify the signal. However this is not a trivial exercise as phase insensitive amplifiers, such as laser ampl...

In this lecture will continue our quantum-mechanical treatment of linear attenuators and linear amplifiers. Among other things, we will distinguish between phaseinsensitive and phase-sensitive amplifiers. We will also show that the attenuator and the phase-insensitive amplifier preserve classicality, i.e., their outputs are classical states when their inputs are classical states. Finally, we wi...

Generation of 1.024-Tb/s Nyquist-WDM phase-conjugated twin vector waves by a polarization-insensitive optical parametric amplifier for fiber-nonlinearity-tolerant transmission.

We experimentally demonstrate the generation of 1.024-Tb/s Nyquist-WDM phase-conjugated vector twin waves (PCTWs), consisting of eight 128-Gb/s polarization-division-multiplexed QPSK signals and their idlers, by a broadband polarization-insensitive fiber optic parametric amplifier. This novel all-optical signal processing approach to generate WDM-PCTWs enables a 2-fold reduction in the needed o...
