Photonic Crystal Fibers for Sensing Applications

open access: yesJournal of Sensors, 2012
Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers present special properties and capabilities that lead to an outstanding potential for sensing applications.

Fabrication Long Period Fiber Bragg Grating Based on Photonic Crystal Fiber Using CO2 Laser

open access: yesمجلة النهرين للعلوم الهندسية
Photonic crystal fibers (PCFs) are generally divided into two categories: solid-core photonic crystal fibers and hollow-core photonic crystal fibers. In this paper, a long-period fiber Bragg grating (LPFBG) was experimentally fabricated in a hollow-core

Observing cross-sectional images and averaged optical patterns of photonic crystal fibers using partially incoherent laser light [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2013
We couple the coherent laser light and the partially incoherent laser light into the photonic crystal fibers, respectively, and compare the observed fiber cross-sectional images.

A new slant on photonic crystal fibers

open access: yesOptics Express, 2004
We present the novel use of microstructured optical fibers not as 'light-pipes', but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques.
