Experimental analysis of four-wave mixing in a semiconductor optical amplifier using frequency resolved optical gating [PDF]
, 2007 Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating.

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 ...

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 ...
