Ultrafast exciton dephasing in PbS colloidal quantum dots [PDF]
, 2011 In this work, we have measured the ground state excitonic dephasing in PbS QDs of sizes from 3.7nm to 5.7nm diameter in the temperature range from 5K to 100K by transient degenerate four-wave mixing (FWM) using 100fs pulses.

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 ...

Wavelength conversion by cavity-enhanced injection-locked four-wavemixing in a fiber-Bragg-grating coupled diode laser [PDF]
, 1998 Four-wave mixing (FWM) in a fiber-Bragg-grating (FBG) coupled semiconductor laser is investigated. We show that a large resonance enhancement of the FWM conversion efficiency can be obtained when the laser cavity is injection-locked by the converted ...

Controllable FWM within a PANDA Ring
Procedia Engineering, 2012 AbstractIn this paper, we present the controllable four-wave mixing (FWM) within PANDA ring resonator based-on optical soliton manipulation. After a dark soliton pulse is fed into an input port of the resonator, the FWM can be formed within the system and detected simultaneously at the output ports.

Harvesting, coupling and control of single exciton coherences in photonic waveguide antennas
, 2016 We perform coherent non-linear spectroscopy of individual excitons strongly confined in single InAs quantum dots (QDs). The retrieval of their intrinsically weak four-wave mixing (FWM) response is enabled by a one-dimensional dielectric waveguide antenna.

IEEE Photonics Journal, 2015 With the homemade solid-core silica-based photonic crystal fiber (PCF), we observe the generation of soliton and four-wave mixing (FWM) when the femtosecond pulse is pumped at 0.822 μm, belonging to the normal-dispersion regime.
