Demonstration of polarization pulling using a fiber-optic parametric amplifier

Demonstration of polarization pulling using a fiber-optic parametric amplifier.

We report the observation of all-optical polarization pulling of an initially polarization-scrambled signal using parametric amplification in a highly nonlinear optical fiber. Broadband polarization pulling has been achieved both for the signal and idler waves with up to 25 dB gain using the strong polarization sensitivity of parametric amplifiers. We further derive the probability distribution...

Activated polarization pulling and de-correlation of signal and pump states of polarization in a fiber Raman amplifier.

We report on a theoretical study of activated polarization pulling and de-correlation of signal and pump states of polarization based on an advanced vector model of a fiber Raman amplifier accounting for random birefringence and two-scale fiber spinning. As a result, we have found that it is possible to provide de-correlation and simultaneously suppress PDG and PMD to 1.2 dB and 0.035 ps/km(1/2...

Demonstration of Polarization Entanglement via Parametric Downconversion

We produce a polarization entangled state via Spontaneous Parametric Downconversion. Photons from a λ = 363.8 nm argon ion laser are incident on orthogonally mounted Beta Barium Borate nonlinear crystals, resulting in polarization entangled photons of λ = 727.6 nm. This state is then probed to determine the purity of entanglement. Introduction Entanglement is one of the most perplexing and coun...
