Waveguide-based cavity ring-down spectroscopy (CRD) can be used for quantitative
measurements of chemical concentrations in small amounts of liquid, in gases or in films …

A general theory for fiber-optic, evanescent-wave spectroscopy and sensors is presented for
straight, uncladded, step-index, multimode fibers. A three-dimensional model is formulated …

A fibre-optic evanescent field absorption sensor based on a U-shaped sensing probe is
described. The influences of fibre core diameter, bending radius of the probe and the …

A comparative experimental study of the fiber-optic evanescent field absorption sensor
based on straight and U-shaped probes is presented. The effects of numerical aperture and …

The evanescent wave absorption based photonic sensing platform has been developed
using D-shaped fiber optic probes for refractive index (RI) mediated bio-sensors. The RI …

We introduce a novel method of chemically removing the cladding of PMMA based polymer
optical fibre (POF) using organic solvents which can also be used to create etched tapers of …

Selectivity or specificity of the biosensors is one of the most important requirements. In
recent years, molecular imprinting technique (MIT) has become very attractive for specific …

An optical fiber, partially stripped of its cladding is shown to sense refractive index of a liquid
in which the uncladded sensing region is immersed, to a high degree of precision and over …

This paper discusses the theoretical and experimental implications of tapering a multimode
optical fiber with a view to its use in evanescent wave absorption spectroscopy. Good …

Multifunctional silica coatings find diverse applications in solar energy conversion and
pollution monitoring sensors due to their suitability for mass manufacturing. However, the …
