Refractive index (RI) of substance, the liquid is an imperative optical measure since it
possesses the optical property of substance and liquid. The simple and precise …

This work demonstrates that the use of an unconventional optical fiber allows for generating
lossy mode resonances (LMRs), without the need for an external high refractive index (RI) …

Biosensors are established as promising analytical tools for detecting various analytes
important in biomedicine and environmental monitoring. Using fiber optic technology as a …

In this work, a three-parameter sensor for the simultaneous measurement of surrounding
refractive index (SRI), temperature and strain is presented. It is based on a single Long …

A high-efficiency grating fabrication method was, for the first time, demonstrated to inscribe
helical long period fiber gratings (H-LPFGs) in small numbers by means of twisting a …

In this work, we report about an ultrasensitive fiber optic biosensor realized using a single-
ended Long Period Grating (LPG). The LPG working point is tuned in the highest sensitivity …

In this work, we report about our recent results concerning the fabrication of Long Period
Grating (LPG) sensors in several optical fibers, through the Electric Arc Discharge (EAD) …

A safe detection of hydrocarbons is a major concern in industrial and public environment,
due to their high volatility and flammability. In this work, we report the development and …

We demonstrate theoretically and experimentally a novel in-fiber Mach-Zehnder
interferometer (MZI) with piecewise interference spectrum. The interferometer is constructed …

In this paper, we report about the fabrication of long period gratings (LPGs) directly into an
Erbium-doped fiber, by using the electric arc discharge technique. The attention is focused …
