|December 7, 2007
Summary
Light can be guided in random holey fibers, challenging previous assumptions. These fibers exhibit single-mode guidance, similar to periodic structures, offering new possibilities for optical technologies.
Area of Science:
- Photonics and Optical Engineering
- Materials Science
Background:
- Holey fibers, characterized by air holes in the cladding, are crucial for advanced optical applications.
- Periodic arrangements of these air holes were previously thought necessary for specific guiding properties like single-mode operation.
Purpose of the Study:
- To provide the first direct confirmation of light guidance in holey fibers with randomly distributed air holes.
- To investigate whether random holey fibers can replicate the single-mode guidance properties of periodic holey fibers.
- To understand the sensitivity of holey fiber optical properties to cladding irregularities.
Main Methods:
- Experimental demonstration of light propagation in a randomly structured holey fiber.
- Optical characterization to assess guiding properties across various wavelengths.
- Comparative analysis with theoretical models and experimental data from periodic holey fibers.
Main Results:
- Direct confirmation that light can indeed be guided in holey fibers with random air hole distribution.
- Demonstration that random holey fibers exhibit single-mode guidance across all wavelengths, a feature previously attributed only to periodic designs.
- Quantification of the influence of specific cladding profile details on the fiber's optical characteristics.
Conclusions:
- Random holey fibers are a viable alternative to periodic ones for achieving specific optical functionalities, including single-mode guidance.
- The findings broaden the design space for fabricating functional optical fibers.
- Understanding the structure-property relationship in random holey fibers is key for future fiber optic innovations.

01:22Fiber Reinforced Concrete
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
00:55Fibrous Proteins
Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
01:11Fibril-associated Collagen
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

01:14Polymer Classification: Architecture
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...
