Towards quantum frequency conversion via non-degenerate four-wave mixing in nanophotonic waveguides

Abstract

Low-noise wavelength conversion through non-degenerate four-wave-mixing Bragg scattering in SiNx waveguides is demonstrated. Two 1550 nm pumps are used to achieve tunable conversion of a 980 nm signal over a range of 10 nm.

Low-noise chip-based frequency conversion by four-wave-mixing Bragg scattering in SiN_x waveguides

Low-noise, tunable wavelength-conversion through nondegenerate four-wave mixing Bragg scattering in SiN(x) waveguides is experimentally demonstrated. Finite element method simulations of waveguide dispersion are used with the split-step Fourier method to predict device performance. Two 1550 nm wavelength band pulsed pumps are used to achieve tunable conversion of a 980 nm signal over a range of 5 nm with a peak conversion efficiency of ≈5%. The demonstrated Bragg scattering process is suitable for frequency conversion of quantum states of light.

Efficient single-photon-level quantum frequency conversion on a silicon nanophotonic chip

Qing Li, Marcelo Davanço, Kartik A. Srinivasan

We demonstrate frequency conversion of single-photon-level signals with an efficiency of 25% and signal-to-noise level >20:1, via four-wave-mixing Bragg scattering in a Si3N4 microring using low power (<20 mW per pump), continuous wave pump lasers.

A chip-scale, telecommunications-band frequency conversion interface for quantum emitters

Imad H. Agha, Serkan Ateş, Marcelo Davanço +1 more

We describe a chip-scale, telecommunications-band frequency conversion interface designed for low-noise operation at wavelengths desirable for common single photon emitters. Four-wave-mixing Bragg scattering in silicon nitride waveguides is used to demonstrate frequency upconversion and downconversion between the 980 nm and 1550 nm wavelength regions, with signal-to-background levels > 10 and conversion efficiency of ≈ -60 dB at low continuous wave input pump powers (< 50 mW). Finite element simulations and the split-step Fourier method indicate that increased input powers of ≈ 10 W (produced by amplified nanosecond pulses, for example) will result in a conversion efficiency > 25 % in existing geometries. Finally, we present waveguide designs that can be used to connect shorter wavelength (637 nm to 852 nm) quantum emitters with 1550 nm.

Intra-cavity frequency shifted laser pumps for non-degenerate and partially coherent Bragg-Scattering FWM in nonlinear fiber

Katarzyna Krupa, Michela Bettenzana, Alessandro Tonello +6 more

Nonlinear effects in fibers with partially coherent pumps have attracted a great interest in view of their potential for polarization insensitive wavelength conversion and the increased resilience to Stimulated Brillouin Scattering [1]. In this work we experimentally study the problem of non-degenerate four-wave-mixing (FWM) by using a pair of partially coherent pumps, and focus our attention on a specific type of FWM, which is generally called “Bragg-Scattering” (BS-FWM). This kind of FWM has attracted a renewed interest because of its intrinsically low-noise nature which makes it potentially applicable for light-by-light manipulation even for very faint signals such as quantum keys [2].

Quantum Frequency Conversion by Four-wave Mixing Using Bragg Scattering

Lasse Mejling, Karsten K. Rottwitt, Colin J. McKinstrie +1 more

Two theoretical models for frequency conversion (FC) using nondegenerate four-wave mixing are compared, and their range of validity are discussed. Quantum-state-preserving FC allows for arbitrary reshaping of states for an appropriate pump selection.
