Coherent Control for a Two-level System Coupled to Phonons

, 1998
The interband polarizations induced by two phase-locked pulses in a semiconductor show strong interference effects depending on the time tau_1 separating the pulses.

Experimental Demonstration of Unified Kerr Nonlinear Effective Lengths for Gallium Phosphide‐On‐Insulator Photonic Devices

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
The four‐wave mixing conversion efficiencies of both the waveguides and the microresonators exhibit a well‐correlated relation versus their effective lengths, confirming the unified theoretical framework. These experimentally validated findings offer a fresh perspective on Kerr nonlinearity and pave the way toward advancing the development of highly ...

Four-Wave Mixing Crosstalk Suppression Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals

The Scientific World Journal, 2014
A new approach to suppressing the four-wave mixing (FWM) crosstalk by using the pairing combinations of differently linear-polarized optical signals was investigated.

ANZCOP ACOFT SPIE Melbourne 2019 GO FWM Waveguides

, 2020
A broadband microwave mixer is demonstrated based on an integrated optical micro-comb source, with an operation bandwidth up to over 60 GHz, a conversion efficiency of −6.8 dB and a spurious suppression ratio of over 43.5 dB, and experimentally verify the RF performance up to 40 GHz. This approach to realizing microwave mixers offers reduced complexity,

RGB generation by four-wave mixing in small-core holey fibers

, 2007
We report the generation of white light comprising red, green, and blue spectral bands from a frequency-doubled fiber laser by an efficient four-wave mixing process in submicron-sized cores of microstructured holey fibers.

Coherent anti-Stokes Raman spectroscopy of single and multi-layer graphene

Nature Communications, 2019
Coherent anti-Stokes Raman Scattering (CARS) accesses the vibrational properties of a material via nonlinear four-wave mixing (FWM); CARS in graphene has not been observed to date despite its high nonlinear third-order susceptibility.

30-nm wavelength conversion at 10 Gbit/s by four-wave mixing in a semiconductor optical amplifier [PDF]

, 1998
Four-wave mixing (FWM) in semiconductor optical amplifiers (SOAs) is currently the only available strictly transparent wavelength-conversion technique, which is not penalized by phase matching.
