Wavefront shaping with nonlinear four-wave mixing [PDF]

Scientific Reports, 2023
Wavefront manipulations have enabled wide applications across many interdisciplinary fields ranging from optics and microwaves to acoustics. However, the realizations of such functional surfaces heavily rely on micro/nanofabrication to define the ...

Simplified Near-Degenerate Four-Wave-Mixing Microscopy [PDF]

Molecules, 2021
Four-wave-mixing microscopy is widely researched in both biology and medicine. In this paper, we present a simplified near-degenerate four-wave-mixing microscopy (SNDFWM).

Dynamics of Fermionic Four-Wave Mixing [PDF]

Physical Review A, 2002
We study the dynamics of a beam of fermions diffracted off a density grating formed by fermionic atoms in the limit of a large grating. An exact description of the system in terms of particle-hole operators is developed.

Frequency comb based four-wave-mixing spectroscopy [PDF]

Optics Letters, 2017
We experimentally demonstrate four-wave-mixing spectroscopy using frequency combs. The experiment uses a geometry where excitation pulses and four-wave-mixing signals generated by a sample co-propagate.

Optically programable quasi phase matching in four-wave mixing [PDF]

Nature Communications
Quasi-phase matching (QPM) enhances nonlinear optical processes by compensating for phase mismatch, but traditional methods require permanent material modifications, limiting applicability in centrosymmetric media like standard optical fibers.

Highly efficient THz four-wave mixing in doped silicon [PDF]

Light: Science & Applications, 2021
Third-order non-linearities are important because they allow control over light pulses in ubiquitous high-quality centro-symmetric materials like silicon and silica.

Generation of pulsed bipartite entanglement using four-wave mixing [PDF]

New Journal of Physics, 2012
Using four-wave mixing in a hot atomic vapor, we generate a pair of entangled twin beams in the microsecond pulsed regime near the D1 line of ^85 Rb, making it compatible with commonly used quantum memory techniques. The beams are generated in the bright

Electromagnetically induced transparency and four-wave mixing in a cold atomic ensemble with large optical depth [PDF]

New Journal of Physics, 2014
We report on the delay of optical pulses using electromagnetically induced transparency (EIT) in an ensemble of cold atoms with an optical depth exceeding 500.

Disorder robust, ultra-low power, continuous-wave four-wave mixing in a topological waveguide [PDF]

Nanophotonics
Four-wave mixing is a widely used nonlinear process for wavelength conversion, parametric amplification and signal regeneration in various Kerr devices, which enables wavelength-tunability and lower-power operation in compact optical systems.
