Four-Wave-Mixing Enhancement in Optical Microfibers [PDF]
Optical Fiber Communication Conference, 2016 Four-Wave-Mixing (FWM) is enhanced by tailoring the modal effective index in optical microfibers to improve the phase matching conditions. An enhancement of >25dB was recorded in a 6-mm-long optical microfiber.

Generation of Phase-Stable Sub-Cycle Mid-Infrared Pulses from Filamentation in Nitrogen
Applied Sciences, 2013 Sub-single-cycle pulses in the mid-infrared (MIR) region were generated through a laser-induced filament. The fundamental (ω1) and second harmonic (ω2) output of a 30-fs Ti:sapphire amplifier were focused into nitrogen gas and produce phase-stable ...

Diffraction manipulation by four-wave mixing
Optics Express, 2015 We suggest a scheme to manipulate paraxial diffraction by utilizing the dependency of a four-wave mixing process on the relative angle between the light fields. A microscopic model for four-wave mixing in a Lambda-type level structure is introduced and compared to recent experimental data.

High-speed hyperspectral four-wave-mixing microscopy with frequency combs
, 2021 A four-wave-mixing, frequency-comb-based, hyperspectral imaging technique that is spectrally precise, potentially rapid, and can in principle be applied to any material, is demonstrated in a near-diffraction-limited microscopy ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Wavelength conversion in a short length of a solid lead-silicate fibre
, 2010 We experimentally demonstrate a four-wave-mixing-based wavelength conversion scheme at 1.55 µm using a 1.1-m length of highly nonlinear, dispersion tailored W-type lead–silicate optical ...

Spurious Four-Wave Mixing Processes in Generalized Nonlinear Schrödinger Equations
, 2023 Numerical solutions of a nonlinear Schrödinger equation may suffer from the spurious four-wave mixing processes. We study how these nonphysical resonances appear in solutions of a much more stiff generalized nonlinear Schrödinger equation with an ...
