Four wave mixing with self-phase matching due to collective atomic recoil [PDF]
, 2004 We describe a method for non-degenerate four-wave mixing in a cold sample of 4-level atoms. An integral part of the four-wave mixing process is a collective instability which spontaneously generates a periodic density modulation in the cold atomic ...

Four-wave mixing in coupled semiconductor quantum dots [PDF]
, 2002 We present a theoretical analysis of four-wave mixing in coupled quantum dots subject to inhomogeneous broadening. For the biexciton transitions a clear signature of interdot-coupling appears in the spectra. The possibility of experimental observation is

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.

Superresolution four-wave mixing microscopy
Optics Express, 2012 We report on the development of a superresolution four-wave mixing microscope with spatial resolution approaching 130 nm which represents better than twice the diffraction limit at 800 nm while retaining the ability to acquire materials- and chemical- specific contrast.

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
