Observation of Angle Switching of Dressed Four-Wave Mixing Image
IEEE Photonics Journal, 2012 We experimentally report that angle-control dynamics in the nonlinear propagation of the images of the probe, generated four-wave mixing (FWM) and fluorescence signals beams in FWM process in a cascade three-level, as well as a two-level atomic systems ...

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]
, 2008 Experimental results are presented demonstrating how four-wave mixing in a semiconductor optical amplifier can be used to remove pulse pedestals introduced due to nonlinearities which occur upon pulse propagation in an optical system.

Four-Wave Optical Parametric Amplification in a Raman-Active Gas
Photonics, 2015 Four-wave optical parametric amplification (FWOPA) in a Raman-active medium is experimentally investigated by use of an air-filled hollow fiber. A femtosecond pump pulse shorter than the period of molecular motion excites the coherent molecular motion of

Degenerate Four-Wave Mixing in Phycoerythrin Dye-Doped Nanoparticles
International Journal of Optics, 2021 We have generated a phase-conjugate (PC) wave from nanoparticles with a new microscopic system proposed. The microscope includes a confocal system with a degenerate four-wave mixing (DFWM) system, which plays a major role in generating the phase ...

Polarization resolved four-wave-mixing-based measurement in bulk material semiconductor optical amplifier [PDF]
, 2006 The anticipated growth in demand for bandwidth leads to the development of all-optical signal processing techniques at ever increasing data rates. One possible candidate to achieve the required performance is the semiconductor optical amplifier (SOA). It

All-Optical Logic Circuits Based on the Polarization Properties of Non-Degenerate Four-Wave Mixing [PDF]
, 2001 This thesis investigates a new class of all-optical logic circuits that are based on the polarization properties of non-degenerate Four-Wave Mixing. Such circuits would be used in conjunction with a data modulation format where the information is coded ...

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 ...
