Optical frequency combs generated by four-wave mixing in a dual wavelength Brillouin laser cavity

open access: yes, 2017
We propose and demonstrate the generation of optical frequency combs via four-wave mixing in a dual wavelength Brillouin laser cavity. When pumped by two continuous-wave lasers with a varied frequency separation, dual wavelength Brillouin lasers with ...

APTES‐Mediated Ti‐Squarate MOF/n‐GaN Nanowire Photoanodes for Efficient Photoelectrochemical Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

Multichannel wavelength conversion using four-wave mixing in semiconductor ring lasers [PDF]

open access: yes, 2012
We theoretically study all-optical simultaneous wavelength conversion of multiple channels by four-wave mixing in semiconductor ring lasers. Locking the semiconductor ring laser to a holding beam allows us to achieve large conversion efficiencies with ...

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Four-wave mixing in EDFAs

open access: yesElectronics Letters, 1999
A study is presented of four-wave mixing (FWM) in L- and C-band EDFAs. From experiments, it has been observed that FWM scales with the length of Er-doped fibre. It is shown theoretically that FWM crosstalk from EDFAs considerably exceeds that from NZDSF fibre in DWDM L-band systems and leads to a penalty of up to 1 dB in terms of the Q parameter.
