Biofuels from the Fresh Water Microalgae Chlorella vulgaris (FWM-CV) for Diesel Engines

open access: yesEnergies, 2014
This work aims to investigate biofuels for diesel engines produced on a lab-scale from the fresh water microalgae Chlorella vulgaris (FWM-CV). The impact of growing conditions on the properties of biodiesel produced from FWM-CV was evaluated.

Optical Vernier Effect Enabled Narrow Linewidth All-Fiber SBS-FWM-Based Tunable Optical Frequency Comb Generation

open access: yesIEEE Photonics Journal, 2023
In this paper, we experimentally demonstrate a low-power, broadband, and narrow linewidth SBS-FWM OFC with tunable line spacing of 50 to 600 GHz. The SBS-FWM OFC spans a bandwidth of $\approx$100 nm over the C$+$L-band region using $\approx$15 dBm pump ...

Coherent Control of Perfect Optical Vortex Through Four-Wave Mixing in an Asymmetric Semiconductor Double Quantum Well

open access: yesFrontiers in Physics, 2022
A scheme for the coherent control of perfect optical vortex (POV) in an asymmetric semiconductor double quantum well (SDQW) nanostructure is proposed by exploiting the tunneling-induced highly efficient four-wave mixing (FWM).

Pump-probe detuning dependence of four-wave mixing pulse in an SOA [PDF]

open access: yes, 2007
Four-wave mixing (FWM) between 2-ps pulses in a multiquantum-well semiconductor optical amplifier (SOA) is presented. The conjugate pulses are fully characterized using the frequency-resolved optical gating technique.

Impact of nonlocal response in plasmonic metasurfaces on four-wave mixing

open access: yesNew Journal of Physics, 2021
We report the impact of nonlocal response in metallic nanostructures on four-wave mixing (FWM) process in nonlinear plasmonic metasurfaces which consist of Au nanostrips coupled with Au film spaced by an ultrathin dielectric film.

Controllable FWM within a PANDA Ring [PDF]

open access: yes, 2012
In 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 ...
