Study of Utilization of Embedded Metal Nanoparticles in Dielectric Thin Film for Humidity Sensing Photonic Sens. (IF 2.073) Pub Date : 2019-09-30 Hala J. El-Khozondar; Waleed S. Mohammed
This paper presents a theoretical study of the utilization of the shift in the reflection peak of the thin dielectric film with embedded metal nanoparticles (NPs) towards humidity and vapor applications. The presence of the NPs in the film results in a complex effective index. Hence, the reflected light at the superstrate-film interface causes a phase shift when the index of the surrounding is changed

Curvature Sensor Based on a Long-Period Grating in a Fiber Ring Resonator Interrogated by an OTDR Photonic Sens. (IF 2.073) Pub Date : 2019-09-30 Regina Magalhães; Susana Silva; Orlando Frazão
The proposed technique demonstrates a fiber ring resonator interrogated by an optical time domain reflectometer (OTDR), for intensity sensing. By using this methodology, a cavity round trip time of 2.85 μs was obtained. For a proof of concept, a long-period grating was inserted in the resonant cavity operating as a curvature sensing device. A novel signal processing approach was outlined, regarding

A Numerical Approach to Design the Kretschmann Configuration Based Refractive Index Graphene-MoS 2 Hybrid Layers With TiO 2 -SiO 2 Nano for Formalin Detection Photonic Sens. (IF 2.073) Pub Date : 2019-09-16 Md. Biplob Hossain; Tamanna Tasnim; Lway F. Abdulrazak; Md. Masud Rana; Md. Rabiul Islam
In this paper, a Kretschmann configuration based surface plasmon resonance (SPR) sensor is numerically designed using graphene-MoS2 hybrid structure TiO2-SiO2 nano particles for formalin detection. In this design, the observations of SPR angle versus minimum reflectance and SPR frequency (FSPR) versus maximum transmittance (Tmax) are considered. The chitosan is used as probe legend to perform reaction

Spectroscopy and Light Emitting Diodes Based System in Characterizing External Beam Therapy 3 Films for Solar Ultraviolet Measurement Photonic Sens. (IF 2.073) Pub Date : 2019-09-16 Wan Insaniah Saleha Ahmad Shah; Ahmad Fairuz Omar
Gafchromic external beam therapy 3 (EBT3) film has widely been used in medical field applications. Principally, the EBT3 film’s color gradually changes from light green to darker color under incremental exposures by ionizing or even non-ionizing ultraviolet (UV) radiation. Peak absorbance of the EBT3 film can be used to predict absorbed doses by the film. However, until today, related researches still

Polydopamine-Assisted Fabrication of Stable Silver Nanoparticles on Optical Fiber for Enhanced Plasmonic Sensing Photonic Sens. (IF 2.073) Pub Date : 2019-09-09 Yiwen Tang; Hui Yuan; Jiangping Chen; Qiguo Xing; Rongxin Su; Wei Qi; Zhimin He
We present a facile and effective method for fabrication of the localized surface plasmon resonance (LSPR) optical fiber sensor assisted by two polydopamine (PDA) layers with enhanced plasmonic sensing performance. The first PDA layer was self-polymerized onto the bare optical fiber to provide the catechol groups for the reduction from Ag+ to Ago through chelating and redox activity. As the reduction

Enhanced Plasmonic-Induced Absorption Using a Cascade Scheme and Its Application as Refractive-Index Sensor Photonic Sens. (IF 2.073) Pub Date : 2019-07-25 Xinyi Li; Daobin Wang; Shoupeng Wang; Lihua Yuan; Jingli Lei; Xiaoxiao Li
In this paper, we describe a new method to improve fast-light transmission, which uses cascades. We design a simple plasmonic device that enables plasmonic-induced absorption (PIA). It consists mainly of two parallel rectangular cavities. The numerical results simulated by using the finite element method (FEM) confirm its function. The corresponding group delay-time can reach –0.146 ps for the PIA

Enhancement of Surface Plasmon Fiber Sensor Sensitivity Through the Grafting of Gold Nanoparticles Photonic Sens. (IF 2.073) Pub Date : 2019-07-16 Elena Miliutina; Yevgeniya Kalachyova; Pavel Postnikov; Vaclav Švorčík; Oleksiy Lyutakov
The optical fibers, coated with plasmonic active metal films, represent the simple and unpretentious sensors, potentially useful for measurements of physical or chemical quantities and wide range of analytical application. All fiber-based plasmonic sensors operate on the same physical principle based on changes in the position of the plasmon absorption peak induced by a variation of surrounding medium
