Microstructured Optical Fibers

Optics and Photonics News, 2002
Microstructured optical fibers have unique properties that offer an opportunity to manipulate light in new ways, providing a platform for a novel class of all-fiber photonic devices. The authors review recent developments in the design and application of microstructured optical fibers for tuning and switching optical signals.

Prospective for biodegradable microstructured optical fibers

Optics Letters, 2006
We report fabrication of a novel microstructured optical fiber made of biodegradable and water soluble materials that features approximately 1 dB/cm transmission loss. Two cellulose butyrate tubes separated with hydroxypropyl cellulose powder were codrawn into a porous double-core fiber offering integration of optical, microfluidic, and potentially ...

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.

Slotted microstructured optical fibers

SPIE Proceedings, 2008
A new type of microstructured optical fiber, with a transverse slot running along its length, has been fabricated from polymethylmethacrylate. The slot exposes the fiber core over long lengths, allowing for materials to be directly introduced into the vicinity of the evanescent waves of the core modes.

Subwavelength Optofluidic Microstructured Optical Fibers

26th Optoelectronics and Communications Conference, 2021
We propose a tapered optofluidic microstructured optical fiber with a subwavelength core, which can provide a promising low-loss subwavelength-scale optofluidic waveguide for various applications.

Polycarbonate hollow-core microstructured optical fiber

Optics Letters, 2008
A hollow-core microstructured polymer optical fiber is fabricated from polycarbonate material and guidance by inhibited coupling in a two-layer structure is demonstrated in two strong transmission bands with minimum losses of 9.0 dB/m at 800 nm and 3.1 dB/m at 1550 nm.

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

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 ...

Hollow-core microstructured polymer optical fiber

Optics Letters, 2006
We have fabricated microstructured polymer optical fibers that guide light in a hollow core using the photonic bandgap mechanism. The hollow core allows the use of polymer fibers to be extended to wavelength ranges where material absorption typically prohibits their use, with attenuation lower than the material loss observed in the infrared.

Modal cutoff in microstructured optical fibers

Optics Letters, 2002
We analyze the nature of modal cutoff in microstructured optical fibers of finite cross section. In doing so, we reconcile the striking endlessly single-mode behavior with the fact that in such fibers all propagation constants are complex. We show that the second mode undergoes a strong change of behavior that is reflected in the losses, effective area,
