Fibre Bragg grating (FBG) pressure sensors show a great potential in replacing conventional
electrical pressure sensors due to their numerous advantages. However, increasing their …

Ethanol is widely used in chemical industrial processes as well as in the food and beverage
industry. Therefore, methods of detecting alcohol must be accurate, precise, and reliable. In …

Abstract Sarin, Soman, and Tabun are man-made nerve agents which were introduced as
vice-regent of chemical battle. As they are extremely dangerous for human health so, it is …

A dual-parameter fiber-optic sensor based on fiber Bragg grating (FBG) cascaded with Fabry–
Pérot interferometer (FPI) structure is described and demonstrated to measure temperature …

An efficient blood component detection process is essential for the diagnosis of hematologic
diseases. This paper presents refractive index-based terahertz (THz) sensing with photonic …

An optical fiber Fabry-Pérot interferometer (FPI) based on an air cavity with a microchannel
is proposed and demonstrated for gas pressure measurement. The inner air cavity is …

Low frequency under-water acoustic signal detections are challenging, especially for marine
applications. A Mach-Zehnder interferometric hydrophone is demonstrated using …

A fiber Fabry–Pérot interferometer (FPI) is proposed and demonstrated for the measurement
of gas pressure and temperature. The interferometer is fabricated by fusion splicing a short …

A fiber Bragg grating (FBG) inscribed Zeonex-based novel, to the best of our knowledge,
side hole polymer optical fiber (SHPOF) is proposed and demonstrated for low gas pressure …

Two photonic crystal fiber structures with quad-core have been investigated in this paper.
Both the structures are geometrically similar but have different background materials. Both …
