One of the new methods of fiber optics uses cladding modes for controlling propagation of
radiation in optical fibers. This paper reviews the results of studies on the propagation …

The use of a complex short-period (Bragg) grating which combines matched periodic
modulations of refractive index and loss/gain allows asymmetrical mode coupling within a …

We study the sensitivity of fiber grating sensors in the applications of strain, temperature,
internal label-free biosensing, and internal refractive index sensing. New analytical …

Waves entering a spatially uniform lossy medium typically undergo exponential intensity
decay, arising from either the energy loss of the Beer–Lambert–Bouguer transmission law or …

A long-period fiber grating (LPFG) humidity sensor is reported utilizing poly (ethylene
oxide)/cobalt chloride (PEO/CoCl_2) as a hybrid hygrosensitive cladding coating. A thin …

A new ethanol vapor detection probe based on an optical fiber long period grating overlaid
with a zinc oxide (ZnO) nanorods layer is presented. The ZnO nanorod layer was developed …

Развитие волоконно-оптической технологии стало важной составной частью
революционного прогресса в области телекоммуникаций. В последние годы были …

We present the polarization dependence of strong asymmetric long period fiber gratings
written on tapered fibers. We found that for off-resonance conditions the spectral response …

A novel sensing configuration for measuring humidity based on a long-period fibre grating
coated with a thin film of silica nanospheres is proposed. The polymeric overlay is deposited …

This work presents a detailed modeling-based analysis of integrated micro-ring resonators
used for absorption spectroscopy. Generally, sensors based on micro-ring resonators detect …
