Tapered Optical Fibres with a Xenon Gas Cladding for Entangled Photon Pair Generation

Abstract

Photon pair generation compatible with quantum memories and telecommunication systems is critical for integration into optical fiber networks. A feasibility study was conducted on the phase-matching conditions necessary for spontaneous four-wave-mixing in tapered single-mode fiber.

Photon-Pair Sources Based on Intermodal Four-Wave Mixing in Few-Mode Fibers

Karsten K. Rottwitt, Jacob G. Koefoed, Erik Nicolai Christensen

Four-wave mixing in optical fibers has been proven to have many applications within processing of classical optical signals. In addition, recent developments in multimode fibers have made it possible to achieve the necessary phase-matching for efficient four-wave mixing over a very wide bandwidth. Thus, the combination of multimode fiber optics and four-wave mixing is very attractive for various applications. This is especially the case for applications in quantum communication, for example in photon-pair generation. This is the subject of this work, where we discuss the impact of fluctuations in core radius on the quality of the heralded single-photon states and demonstrate experimental results of intermodal spontaneous four-wave mixing for photon-pair generation.

Fiber entangled photon pair source connecting telecom to quantum memories

Ronald E. Meyers, Sanjit Karmakar, Keith S. Deacon +1 more

A fiber optic based source of polarization entangled photon pairs is proposed to connect and entangle a telecom quantum memory to a solid state quantum memory based on single-qubits operating in the near infrared. To span this large wavelength difference while matching the narrow spectral bandwidth of the quantum memories, the photon pairs are generated by four wave mixing in a highly birefringent fiber. Raman noise is expected to be strongly suppressed under these conditions.

Influence of fibre homogeneity on Four Wave Mixing pair generation

Thibault Harlé, Margaux Barbier, Martin Cordier +4 more

Summary form only given. Optical fibre (either classical or microstructured) is a favourable medium for realization of sources of entangled photons for quantum communications. Indeed the photon pairs are generated through spontaneous Four Wave Mixing (FWM) directly in the fibre core and can thus be connected easily and without loss to the optical telecommunication network.We have realized such a source and characterized its performance. Our measurements showed a photon pair generation rate lower than expected in theory. Further characterization showed, as can be seen in Fig. 1A, a widened pair spectrum and a diminution of the generation rate compared to the prediction of our model (Fig. 1B) [2]. Such features can be explained by taking in account the intrinsic inhomogeneity of the fibre, i.e. the core and cladding dimensions fluctuation along the fibre. Indeed, a small variation of the fibre diameter implies a slightly different dispersion, hence shifted photon pair frequencies. To depict these uniformities, we extended our model through a similar approach as in Ref. [3], considering the fibre as an assembly of homogeneous sections, each one with its own length and phase mismatch. Consequently, the joint spectral intensity of pairs describing their generation probability for a given couple of frequencies is more complex. In Fig. 1B, we show the result of our numerical simulation for a purely uniform fibre with parameters corresponding to our source [1,2], and in the case of a linear variation of the zero dispersion wavelength along the fibre. In this specific case, a new analytical solution that will be presented, can be derived from our model, and is also shown in Fig. 1B as a comparison.
