Design of nanofibres for efficient stimulated Raman scattering in the evanescent field

, 2013
Nanofibres can be produced with diameters smaller than the wavelength of the light they guide. In this regime, the guided mode presents a strong evanescent field well adapted to the excitation of “evanescent nonlinearitiesâ€.

Effect of tin on bandgap narrowing and optical properties of ZnO–Zn2SnO4 electrospun nanofibre composite

Journal of Taibah University for Science, 2020
The quest for improved visible light absorption in ZnO-based photocatalysts and photodetectors is a prevailing research problem. One method of solving this problem is by narrowing the band gap of this material well into the range of visible light energy.

Synthesis of electrospun nanofibrous structures with controlled optical and electrical properties [PDF]

AIP Advances, 2020
In this study, the optical and electrical influences of 2D graphene flakes in electrospun polycaprolactone (PCL) fibers were observed. Graphene nanoplatelets were added in different concentrations into the PCL solution, and then, using the electrospinning technique, fibers were built from that solution.

Scattering approach to two-colour light forces and self-ordering of polarizable particles

New Journal of Physics, 2014
Collective coherent scattering of laser light by an ensemble of polarizable point particles creates long-range interactions, whose properties can be tailored by the choice of injected laser powers, frequencies, and polarizations. We use a transfer matrix

Temperature measurement of cold atoms using transient absorption of a resonant probe through an optical nanofibre

, 2016
Optical nanofibres are ultrathin optical fibres with a waist diameter typically less than the wavelength of light being guided through them. Cold atoms can couple to the evanescent field of the nanofibre-guided modes and such systems are emerging as ...
