Kfir Sulimany, Yaron Bromberg

We use spontaneous four wave mixing to generate multimode photon pairs in a few mode fiber. We show the photons are correlated in the fiber mode basis using an all-fiber mode sorter.

All-fiber source and sorter for multimode correlated photons

Kfir Sulimany, Yaron Bromberg

Abstract Photons occupying multiple spatial modes hold a great promise for implementing high-dimensional quantum communication. We use spontaneous four-wave mixing to generate multimode photon pairs in a few-mode fiber. We show the photons are correlated in the fiber mode basis using an all-fiber mode sorter. Our demonstration offers an essential building block for realizing high-dimensional quantum protocols based on standard, commercially available fibers, in an all-fiber configuration.

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.Four-wave mixing in optical fibers has been proven to have many applications within processing of classical optical signals.

We generate photon pairs at 1550 nm telecom through the intermodal four-wave mixing between LP01 and LP11 mode in a few-mode fiber. The ratio of coincidence to accidental coincidence rates is measured to be 28.
