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 ...

Nonlinear four-wave mixing with enhanced diversity and selectivity via spin and orbital angular momentum conservation

, 2020
Light that can carry orbital angular momentum (OAM) has found a variety of applications in super-resolution microscopy, optical communications, and laser machining, bringing up the need for pure OAM light generation at on-demand power levels and ...

Real-Time Waveform Characterization by Using Frequency-Resolved Optical Gating Capable of Carrier-Envelope Phase Determination

IEEE Photonics Journal, 2014
We present real-time waveform characterization of ultrashort pulses by the use of a pulse-front tilt in frequency-resolved optical gating capable of carrier-envelope phase determination.

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 ...

All Optical Signal-Processing Techniques Utilizing Four Wave Mixing

Photonics, 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 ...

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
