Photonic crystal fiber metalens [PDF]
Nanophotonics, 2019 Conventional optical fiber has excellent performance in guiding light, which has been widely employed for long-distance optical communication. Although the optical fiber is efficient for transmitting light, its functionality is limited by the dielectric ...

Topological photonic crystal fiber. [PDF]
Sci AdvPhotonic crystal fibers (PCFs) provide a versatile platform for various applications, thanks to the flexibility with which light guiding can be customized by modifying the fiber geometry. We realize a PCF with guided modes produced by photonic band structure topology rather than conventional mode-trapping mechanisms.

Hydrophobic photonic crystal fibers [PDF]
Optics Letters, 2011 We propose and demonstrate hydrophobic photonic crystal fibers (PCFs). A chemical surface treatment for making PCFs hydrophobic is introduced. This repels water from the holes of PCFs, so that their optical properties remain unchanged even when they are immersed in water.

Topological supermodes in photonic crystal fiber. [PDF]
Sci Adv, 2022 Topological states enable robust transport within disorder-rich media through integer invariants inextricably tied to the transmission of light, sound, or electrons. However, the challenge remains to exploit topological protection in a length-scalable platform such as optical fiber.

Acta Physica Polonica A, 2004 Photonic crystal fibers are a new class of optical fibers. Their artificial crystal-like microstructure results in a number of unusual properties. They can guide light not only through a well-known total internal reflection mechanism but using also photonic bandgap effect. In this paper different properties possible to obtain in photonic crystal fibers

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

Fiber fuse in chalcogenide photonic crystal fibers [PDF]
Optics Letters, 2018 We observe fiber fuse in tapered GeAsSe photonic crystal fibers (PCF) at around 7 MW/cm2 of intra-core intensity. Vertically cleaved facets from the un-tapered regions and the tapered regions were imaged. The images show shallow voids of different shapes confined to the fiber core. After longitudinally polishing a segment of the PCF, we imaged the PCF

Dispersion in a Gas Filled Hollow Core Photonic Crystal Fiber
مجلة بغداد للعلوم, 2014 Hollow core photonic bandgap fibers provide a new geometry for the realization and enhancement of many nonlinear optical effects. Such fibers offer novel guidance and dispersion properties that provide an advantage over conventional fibers for various ...

Optics Express, 2006 We present a hybrid photonic crystal fiber in which a guided mode is confined simultaneously by modified total internal reflection from an array of air holes and antiresonant reflection from a line of high-index inclusions. Experimental results demonstrate that this fiber shares properties of both index-guided and photonic bandgap structures.
