A novel, perfectly hexagonal lattice photonic crystal fiber (PCF) biosensor based on surface
plasmon resonance (SPR) is proposed in this research. To design and investigate the …

In this manuscript, we present a unique and simply designed surface plasmon resonance-
based PCF biosensor that shows high sensing performance. The numerical technique finite …

Refractive index (RI) is a unique attribute of bio-analytes which highly relies upon their
concentrations or the activity/infectivity of the microbes. In this paper, a dual-polarized …

We proposed a hybrid tilted fiber gratings (polarizing grating and tilted fiber Bragg grating)-
based surface plasmon resonance (SPR) sensor. The hybrid tilted fiber grating, consisting of …

In this article, a quasi-second-order Lyot-Sagnac filter is theoretically and experimentally
developed by applying the partial-bias-twisting in a polarization maintaining fiber based …

A vibration sensor based on Sagnac interferometer and fiber ring laser (FRL) is proposed for
fault diagnosis of bearing, and a sensing system of vibration is demonstrated experimentally …

We proposed and demonstrated a method to improve the birefringence of tilted fiber Bragg
gratings (TFBGs) via high-refractive-index indium tin oxide (ITO) coatings. Firstly, we find the …

The optical fiber curvature sensor is an important device that is widely used in the field of
medical instruments. In this paper, we proposed a high sensitivity curvature sensor based on …

A solid unobtrusive fiber-optic sensor based on modal interference in dual mode fiber (DMF)
embedded in a thin mat is proposed and investigated theoretically and experimentally …

In this paper, a comprehensive passive torsion measurement is performed firstly in a 40-cm-
long polarization maintaining fiber-based Sagnac interferometer (PMF-SI), and the non …
