Wavelength dependence of equilibrium mode distribution and steady state distribution in W-type plastic-clad silica fibers
(Elsevier, 2019-11-27)
Wavelength dependence of equilibrium mode distribution (EMD) and steady state distribution (SSD) in W-type
plastic-clad silica fibers (PCSFs) is investigated in this paper for parametrically varied width of the fiber’s ...
Controlling the bandwidth of W-type plastic-clad silica optical fibers
(IOP Publishing, 2019-06-27)
A new design of a multimode plastic-clad silica optical fiber that takes the characteristic
W-shaped index profile is proposed. The bandwidth and steady-state loss are determined
for such a W-type plastic-clad silica ...
An Overview of Novel Methods for ASEP Performance Evaluation Based on Q-Function Approximation
(27th Telecommunications forum TELFOR 2019, 2019-11-27)
The closed-form expression for Q-function does not exist so it is necessary to develop its approximation in order to overcome the difficulties that might appear in diverse
research areas. In this paper the authors are ...
Power flow in multimode step-index plastic photonic crystal fibers
(Elsevier, 2021-08-21)
We investigate the state of mode coupling in a multimode step-index plastic photonic crystal fiber
(SI PPCF) with a solid-core by solving the time-independent power flow equation. For various
arrangements of air-holes, ...
Influence of mode coupling on three, four and five spatially multiplexed channels in multimode step-index plastic optical fibers
(Elsevier, 2018-04-04)
We investigate the influence of mode coupling on space division multiplexing capability of three multimode step-index plastic optical fibers with different strengths of mode coupling. Results show that mode
coupling ...
Enhanced bandwidth of W type plastic optical fibers designed from singly clad step index plastic optical fibers
(Elsevier, 2018-11-02)
We propose a multimode W type (doubly clad) plastic optical fiber which takes the characteristic W-shaped index profile designed from a multimode singly clad step index plastic optical fiber upon modification of the cladding ...
Power Flow in Graded-Index Plastic Optical Fibers
(IEEE, 2019-07-03)
A method is proposed for predicting the evolution of the power distribution along graded-index plastic optical fibers. This method is verified against our recently reported measurements. The strong influence of mode coupling ...
A GIS-based method for analysis of a better utilization of thermal-mineral springs in the municipality of Kursumlija (Serbia)
(Elsevier, 2018-09-02)
There are about 240 geothermal occurrences with 60 commercial spas included in, which are spread throughout the territory of Serbia. The majority of springs and other surface manifestations are located along the south-eastern ...
