Abstract

Using intermodal four-wave mixing (FWM) in an optical step-index fiber, we demonstrate a process capable of generating photon pairs with low spectral correlations without the need for optical filtering of the FWM sideband.

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.

Intermodal-Vectorial Four-Wave Mixing in Few-Mode Fibers for Generation of Photon Pairs with Spatial-Polarization-Frequency Hybrid Entanglement

Four-wave mixing (FWM) in optical fibers is a nonlinear optical process which can be used to generate photon pairs with hybrid entanglement in multiple degrees of freedom (DOFs), including frequency, polarization, spatial mode, or angular momentum [1]. Until now, the realizations of entanglements in the DOFs: energy-time, frequency, polarization, spatial-frequency, and polarization-frequency [1] have been proposed using specific FWM processes in different optical fibers.
