Unusual Scenarios in Four-Wave-Mixing Instability

open access: yes, 2022
A pump carrier wave in a nonlinear dispersive system may decay by giving birth to blue- and redshifted satellite waves due to modulation or four-wave mixing instability.

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]

open access: yes, 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

open access: yesPhotonics, 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

open access: yesInternational 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]

open access: yes, 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]

open access: yes, 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

open access: yesEPJ 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 ...

All Optical Signal-Processing Techniques Utilizing Four Wave Mixing

open access: yesPhotonics, 2015
Four Wave Mixing (FWM) based optical signal-processing techniques are reviewed. The use of FWM in arithmetical operation like subtraction, wavelength conversion and pattern recognition are three key parts discussed in this paper after a brief ...
