Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers
(MDPI, 2017-12-20)
The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization ...
Fabrication of Active Polymer Optical Fibers by Solution Doping and Their Characterization
(MDPI, 2018-12-31)
This paper employs the solution-doping technique for the fabrication of active polymer optical fibers (POFs), in which the dopant molecules are directly incorporated into the core of non-doped uncladded fibers. Firstly, ...
Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers
(MDPI, 2017-03)
The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied. The work includes a detailed analysis of the amplified ...
POF-Based Solar Concentrators Incorporating Dyes and Europium Chelates
(MDPI, 2021-05-19)
In this paper, useful models that enable time-efficient computational analyses of the performance of luminescent solar concentrators (LSCs) are developed and thoroughly described. These LSCs are based on polymer optical ...
Effects of Fabrication Methods on the Performance of Luminescent Solar Concentrators Based on Doped Polymer Optical Fibers
(MDPI, 2021-01-28)
In this work, we detail two types of fabrication processes of four polymer optical fibers doped with lumogen dyes. The fiber preforms have been manufactured with two different methods: extrusion and casting. We have compared ...
Crank-Nicholson method for rate equations in powder random lasers
(IOP Publishing, 2015)
In this work, we show the resolution of the rate equations in powder random lasers by using the Crank-Nicholson finite difference method. Light propagation in our powders is described by the model of light diffusion. The ...
Theoretical Modeling of Viscosity Monitoring with Vibrating Resonance Energy Transfer for Point-of-Care and Environmental Monitoring Applications
(MDPI, 2018-12-21)
Forster resonance energy transfer (FRET) between two molecules in nanoscale distances is utilized in significant number of applications including biological and chemical applications, monitoring cellular activities, sensors, ...
Simultaneous Sensing of Refractive Index and Temperature With Supermode Interference
(IEEE, 2021-11-15)
[EN]In general, a sensor is used to monitor a single parameter only, and in many cases, a reference sensor is necessary to compensate the effect of temperature. Here, we demonstrate that a single supermode interferometer ...
High-performance vector bending and orientation distinguishing curvature sensor based on asymmetric coupled multi-core fibre
(Nature, 2020-08-20)
Fibre optic technology is rapidly evolving, driven mainly by telecommunication and sensing applications. Excellent reliability of the manufacturing processes and low cost have drawn ever increasing attention to fibre-based ...
Study of the Influence of Various Stress-Based Mechanisms on Polarization of an SM mPOF for the Development of Useful Devices
(IEEE, 2017-07-15)
In contrast to conventional polymer optical fibres (POFs), single-mode microstructured POFs (SM mPOF) exhibit polarization properties that make them potentially interesting for their use in the design and development of ...
