Near-Field Characterization of Optical Micro/Nanofibres

Chinese Physics Letters, 2007
Near-field scanning optical microscopy is used to investigate the waveguiding properties of optical micro/nanofibres (MNFs) by means of detecting optical power carried by evanescent waves. Taper drawn silica and tellurite MNFs, supported on low-index substrates, are used to guide a 532-nm-wavelength light beam for the test.

Optical transparency of electrospun nanofibrous membranes: A study on influencing parameters

Journal of Applied Polymer Science, 2023
AbstractThis paper studies the effects of five parameters, including fiber diameter, crystallinity, thickness, packing density, and surface roughness, on the transparency of electrospun polymethyl methacrylate/polydimethylsiloxane (PMMA/PDMS) nanofibrous membranes after heat treatment.

Few Atom Detection and Manipulation Using Optical Nanofibres

2010
We study the coupling of spontaneously emitted photons from laser-cooled 85Rb atoms to the guided modes of an optical nanofibre to demonstrate the potential such fibres offer as tools for detecting and manipulating cold atoms, even when the number of atoms is very small.

Electrospun Nanofibrous Membranes for Highly Sensitive Optical Sensors

Nano Letters, 2002
The first use of electrospun nanofibrous membranes as highly responsive fluorescence quenching-based optical sensors for metal ions (Fe3+ and Hg2+) and 2,4-dinitrotoluene (DNT) is reported. A fluorescent polymer, poly(acrylic acid)−poly(pyrene methanol) (PAA−PM), was used as a sensing material.

Transparent Nanofibrous Membranes with Optimized Optical Channel Structure for Window Screens

Advanced Materials Technologies
AbstractNanofibrous membranes, characterized by their flexibility, high porosity, and tunable structure, are emerging as a promising contender for advanced transparent materials with sufficient breathability and pliability. However, the considerable surface light reflection and internal light scattering of nanofibrous membranes pose a challenging task ...

Nanofibrous membranes for visual and optical monitoring: a focus on pH-sensors

2014
It is clear that nanofibres can be used for several sensor applications due to the inherent properties linked to their nanoscale diameters. Nanofibrous materials have improved sensor sensitivity mainly due to the large surface area to volume ratio, providing an increased number of sites for analyte interaction or signal transduction [1,2]. The possible
