Recent developments in microstructured optical fibers and optical fiber glasses

SPIE Proceedings, 2008
In the last ten years, the development of air-silica microstructured fibers has opened an exciting route to study new type of optical waveguides, leading to a wide range of applications. Now, the possibility offer by this photonic technology to incorporate original materials and mix different fabrication processes give a promising way to adapt the ...

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 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

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 ...

Optical Aging of Chalcogenide Microstructured Optical Fibers

Journal of Lightwave Technology, 2014
The evolution with time of optical transmission of chalcogenide microstructured optical fibers has been studied. Microstructured optical fibers with “grapefruit” geometry (six holes) have been prepared from four glass compositions (Te20As30Se50, As38Se62, Ge10As22Se68, and As40S60).

Nonlinear optics of microstructure fibers

Uspekhi Fizicheskih Nauk, 2004
Microstructure fibers have opened a new phase in nonlinear optics. Due to their unique properties, fibers of this type radically enhance all the basic nonlinear-optical phenomena, offering new strategies for frequency conversion, spectral transformation, and control of ultrashort laser pulses.

Chromatic dispersion and losses of microstructured optical fibers

Applied Optics, 2003
Using a rigorous and vector multipole method, we compute both losses and dispersion properties of microstructured optical fibers with finite cross sections. We restrict our study to triangular lattices of air-hole inclusions in a silica matrix, taking into account material dispersion. The fiber core is modeled by a missing inclusion.

Vortex Supported Waveguiding in Microstructured Optical Fibers

2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020
In this paper, we propose a mechanism of vortex formation in the transverse components of the Poynting vector of the core modes in different types of optical fibers. It is shown that vortex formation in the transverse component of the Poynting vector occurs when real and imaginary parts of axial components of electric and magnetic fields of the core ...

Highly tunable birefringent microstructured optical fiber

Optics Letters, 2002
We demonstrate a method for introducing and dynamically tuning birefringence in a microstructured optical fiber. Waveguide asymmetry in the fiber is obtained by selective filling of air holes with polymer, and tunability is achieved by temperature tuning of the polymer's index. The fiber is tapered such that the mode field expands into the cladding and

Microstructured optical fiber Bragg gratings and their applications

Proceedings of the 2008 International Conference on Advanced Infocomm Technology - ICAIT '08, 2008
Bragg gratings are inscribed in a highly Ge-doped index-guiding microstructured optical fiber, a grapefruit microstructure fiber, and an all-solid bandgap fiber, by conventional phase mask method. Their spectral characteristics and couplings are explained based on coupled mode theory and the analysis of their modal properties.
