Four-photon scattering in birefringent fibers

Edouard Brainis

Four-photon scattering in nonlinear waveguides is an important physical process that allows photon-pair generation in well-defined guided modes, with high rate and reasonably low noise. Most of the experiments to date used the scalar four-photon scattering process in which the pump photons and the scattered photons have the same polarization. In birefringent waveguides, vectorial four-photon scatterings are also allowed: these vectorial scattering processes involve photons with different polarizations. In this paper, the theory of four-photon scattering in nonlinear, birefringent, and dispersive fibers is developed in the framework of the quantum theory of light. The work focuses on the spectral properties and quantum correlations (including entanglement) of photon pairs generated in high-birefringence and low-birefringence fibers.

Photon Pair Generation via Spontaneous Four-Wave Mixing in Birefringent Optical Fibers

Brian J. Smith, Pierre Mahou, Offir Cohen +2 more

We experimentally demonstrate photon pair production in standard single-mode optical fibers via spontaneous four-wave mixing. The process utilizes birefringent phase matching to control the photon pair joint spectral structure.

Role of Raman Scattering on Correlated Photon Pairs Generated Through Four-Wave Mixing

Qinglong Lin, Govind Prasad Agrawal

We discuss photon-pair correlation under the combined effects of four-wave mixing and Raman scattering inside optical fibers and silicon waveguides. Our theory is vectorial in nature and includes all polarization effects.

Photon pair generation in birefringent optical fibers

Brian J. Smith, Pierre Mahou, Offir Cohen +2 more

We study both experimentally and theoretically the generation of photon pairs by spontaneous four-wave mixing (SFWM) in standard birefringent optical fibers. The ability to produce a range of two-photon spectral states, from highly correlated (entangled) to completely factorable, by means of cross-polarized birefringent phase matching, is explored. A simple model is developed to predict the spectral state of the photon pair which shows how this can be adjusted by choosing the appropriate pump bandwidth, fiber length and birefringence. Spontaneous Raman scattering is modeled to determine the tradeoff between SFWM and background Raman noise, and the predicted results are shown to agree with experimental data.

Roles of fiber birefringence and Raman scattering in the spontaneous four-wave mixing process through birefringent fibers

Mengyu Xie, Youn Seok Lee, Ramy Tannous +2 more

We investigate the impact of fiber birefringence and spontaneous Raman scattering on the properties of photon pairs that are generated by the spontaneous four-wave mixing process in birefringent fibers. Starting from the formulation of the theory of four-wave mixing, we show a theoretical model for a generated optical field with the consideration of the Raman scattering and a Gaussian-distributed pump. The theoretical model is then applied for deriving the closed expressions of the photon-pair spectral properties as a function of the fiber birefringence. Also, with the modeled Raman gain, we evaluate the reduction of the pair production rate due to the presence of the Raman effect as well as the contributions of the Raman-scattered photons over a broad wavelength range. The predictions are experimentally verified with a commercial polarization-maintaining fiber.

Effects of polarization-dependent loss and fiber birefringence on photon-pair entanglement in fiber-optic channels

Milja Medić, Prem Kumar

Quantum communication requires that photon-pair entanglement be preserved as the photons are distributed to remote locations. We model the effects of loss and birefringence on polarization-entangled photon pairs propagating in optical fibers.
