RGB generation by four-wave mixing in small-core holey fibers [PDF]
, 2007 We report the generation of white light comprising red, green, and blue spectral bands from a frequency-doubled fiber laser by an efficient four-wave mixing process in submicron-sized cores of microstructured holey fibers.

Spontaneous Four-Wave Mixing in an Irregular Nanofiber
EPJ Web of Conferences, 2015 The features of biphotons states generated via spontaneous four-wave mixing in nanofibers with a variable cross-section are studied. The spectral amplitude of the biphoton field is calculated and the effects of interference and phase modulation of the ...

Dynamics of fermionic four-wave mixing [PDF]
Physical Review A, 2003 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. We use a combination of analytical and numerical methods to quantitatively explore the Raman-Nath and the Bragg regimes of ...

A novel four-wave mixing compensator [PDF]
SPIE Proceedings, 2006 We propose and demonstrate a novel four-wave-mixing (FWM) compensator made of a highly nonlinear fiber and a pump laser. This technique utilizes the additional pi/2 phase delay occurring in every FWM process. Thus, the FWM components generated in the transmission fiber can be cancelled out by the FWM components generated within the FWM compensator.

Spectrally resolved wave-mixing between near- and far-infrared pulses in gas [PDF]
, 2013 We investigate the nonlinear wave-mixing in gases between intense, short optical pulses and long-wavelength fields (mid infrared and terahertz). We show numerically that the beating between the sum- and difference-frequency generation components can be ...

Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing
New Journal of Physics, 2019 Plasmonic waveguides are an essential element of nanoscale coherent sources, including nanolasers and four-wave mixing (FWM) devices. Here we report how the design of the plasmonic waveguide needs to be guided by the ultimate application.

Nanoscale dynamics by short-wavelength four wave mixing experiments
New Journal of Physics, 2013 Multi-dimensional spectroscopies with vacuum ultraviolet (VUV)/x-ray free-electron laser (FEL) sources would open up unique capabilities for dynamic studies of matter at the femtosecond–nanometer time–length scales. Using sequences of ultrafast VUV/x-ray
