Abstract

We describe a scheme for generation of spatial-mode-entangled photon pairs in a few-mode fiber and experimentally demonstrate generation of idler beams from classical seed signals representing various superpositions of fiber LP01and LP11amodes. For every signal mode superposition, we observe the indication of idler mode orthogonality to the signal mode.

Aiming at producing spatial-mode-entangled photon pairs in a few-mode fiber, we experimentally demonstrate generation of idler beam from a seed signal in a superposition of two fiber modes. For every signal mode superposition, we observe the indication of idler mode orthogonality to the signal mode.

Generation of polarization entangled photon pairs by using polarization- and transverse-mode maintaining few-mode fiber

Shengjie Zhu, Liang Cui, Xiaoying Li

Polarization entangled signal and idler photons in the higher-order LP11a and LP11b modes, respectively, are generated via inter-spatial-mode spontaneous four-wave mixing in a 17-m-long mode maintaining few-mode fiber with a panda type elliptical core.

Optimized entangled photon pair generation via intermodal four-wave mixing in a telecommunication-length few-mode fiber

Seyedehnajmeh Montazeri, Mina Esmaeelpour

We report our recent progress in generating and verifying entangled photon pairs in a telecommunication-length few-mode fiber using spontaneous four-wave mixing in a non-degenerate pump configuration. We demonstrate through seeding the desired four-wave mixing effect for pair production in the presence of a strong mode-coupling when using integrated mode multiplexers known as photonic lanterns. The mode content and phase-matching requirements were validated through computations and experiments. We discuss the challenges and requirements for phase matching and photon visibility without modifying the fiber structure. This work represents our first steps toward an efficient tunable source of entangled photons for space division multiplexing applications.

Polarization-entangled photon generation in multimode fiber at visible wavelength

Kyungtaek Lee, Ikjun Hong, Ju Han Lee

We experimentally demonstrate the generation of polarization-entangled photons at visible wavelengths through a spontaneous four-wave mixing process. Polarization entangled photon pair is created by pumping multimode fiber inside a Sagnac loop. The central wavelength and the efficiency of the generated signal and idler photons of different spatial modes are studied. We observed two-photon interference with visibility >92.4% for LP11 spatial modes of signal and idler photon at the wavelength of 456 nm and 633 nm, respectively.
