Mechanical Strength of Microstructured Optical Fibers

Journal of Lightwave Technology, 2014
An experimental study of the mechanical reliability of microstructured optical fibers (MOFs) is reported. Tensile tests were carried on five types of MOFs and two reference fibers, and the tensile strengths were analyzed using Weibull statistics. Optical microscopy of the surfaces of rupture allowed identifying the critical flaws and determining the ...

Resonance and scattering in microstructured optical fibers

Optics Letters, 2002
We present an investigation into the mechanism for guidance of microstructured optical fibers consisting of high-refractive-index cylinders embedded in a low-index background. A new guidance regime is identified in which the fibers' confinement losses depend strongly on wavelength and the positions of the loss minima and maxima depend on the scattering

Optical properties of microstructured optical fibers

SPIE Proceedings, 2004
ABSTRACT In conventional optical fibers the light guiding and other optical properties are mainly controlled by the index profile as given by the composition of the doping materials. In this case technological and material properties limit the design flexibility of the optical properties. For example, it is not possible to shift the region of anomalous

Microstructured Optical Fibers for chemical and biological analysis

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
A hybrid biosensing platform based on a Peptide Nucleic Acid - functionalized Microstructured Optical Fibers Bragg gratings for DNA detection has been implemented. The inner surface of different MOFs has been functionalized using PNA probes, an artificially synthesized polymer that is well suited for specific DNA target sequences detection. In order to

Transverse light guides in microstructured optical fibers

Optics Letters, 2006
A novel class of microstructured optical fiber coupler is introduced that operates by resonant, rather than proximity, energy transfer by means of transverse light guides built into a fiber cross section. Such a design permits significant spatial separation between interacting fibers, which, in turn, eliminates intercore cross talk owing to proximity ...

Microstructured Optical Fibers

2006
This chapter explores microstructured optical fibers that have now developed to the point where they are not only of interest from a research perspective, but are also becoming available commercially. This chapter demonstrates that good quality index guiding holey fibers (HFs) and photonic bandgap fibers (PBGFs) based on a cladding structure with a ...

Optical Properties of Microstructure Optical Fibers

2003
The development of optical-fiber cables and communications technology has undergone a dramatic revolution over the past decade [1]. The most basic design of an optical fiber consists of silica cladding that surrounds a silica core doped with germanium (GeO2), which increases the index of refraction by up to 2% above that of pure silica, allowing light ...

Microstructured Optical Fiber Sensors

Journal of Lightwave Technology, 2017
In this paper, a review of microstructured optical fiber (MOF) sensors is given. Various kinds of MOFs are described and their sensing applications are summarized. Two main types of MOF sensors in terms of grating based and interferometry based are reviewed.

Optical fiber gratings written in microstructured optical fibers

2012 Photonics Global Conference (PGC), 2012
Microstructured optical fibers are usually divided into two different types of fibers: solid-core Photonic crystal fibers (PCFs) and air-core photonic bandgaps fibers (PBGs). This paper presents the fabrication methods and applications of optical fiber gratings written in both solid-core PCFs and air-core PBGs. A sensitive stain sensor was demonstrated

Chalcogenide microstructured optical fibers

2012 Photonics Global Conference (PGC), 2012
Chalcogenide glasses are known for their large transparency in the mid-infrared and their high linear refractive index (>2). They present also a high non-linear coefficient (n 2 ), 100 to 1000 times larger than for silica, depending on the composition. we have developed a casting method to prepare the chalcogenide preform.
