Observation of Angle Switching of Dressed Four-Wave Mixing Image
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]
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.

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

Four-Wave Optical Parametric Amplification in a Raman-Active Gas
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
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]
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]
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
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]
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 ...
