Multimaterial photonic crystal fibers [PDF]
Optical Components and Materials XV, 2018 One of the main advantages of photonic crystal fibers (PCFs) is their ability to host novel functional materials in the airholes of the cladding. Here, we demonstrate a unique post-processing method which allows the integration of materials with significantly different thermo-mechanical properties inside the voids of silica PCF.

Polarization maintaining large mode area photonic crystal fiber [PDF]
Opt. Express 12, 956 (2004)., 2004 We report on a polarization maintaining large mode area photonic crystal fiber. Unlike, previous work on polarization maintaining photonic crystal fibers, birefringence is introduced using stress applying parts. This has allowed us to realize fibers, which are both single mode at any wavelength and have a practically constant birefringence for any ...

Design of a highly-birefringent microstructured photonic crystal fiber for pressure monitoring [PDF]
, 2010 We present the design of an air hole microstructured photonic crystal fiber for pressure sensing applications. The air-hole photonic crystal lattices were designed to produce a large intrinsic birefringence of 1.16x10-3. The impact of the surrounding air

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

Single-mode photonic crystal fiber with an effective area of 600 square-micron and low bending loss [PDF]
Electronics Letters 39, 1802 (2003)., 2003 A single-mode all-silica photonic crystal fiber with an effective area of 600 square-micron and low bending loss is demonstrated. The fiber is characterized in terms of attenuation, chromatic dispersion and modal properties.

D-Shaped Photonic Crystal Fiber Toxic Metal Ions (Arsenic) Sensor Based on Surface Plasmon Resonance
Iraqi Journal of Physics, 2023 In this work, a Photonic Crystal Fiber (PCF) sensor based on the Surface Plasmon Resonance (SPR) technology was proposed. A thin layer of gold (Au) was deposited on a D-shaped Photonic Crystal Fiber (PCF), which was coated with plasmonic chemically ...

Two-photon interference of photon pairs created in photonic crystal fibers [PDF]
J. Phys. Soc. Jpn. 78 (2009) 024402, 2009 We investigate a method to produce photon pairs by four-wave mixing in photonic crystal fibers (PCFs). By controlling the wavelength of the pump light, which determines the phase matching condition for four-wave mixing, we can obtain a broader spectrum of photon pairs than undesired Raman-scattered photons.

Micro-Displacement Sensor Based on a Hollow-Core Photonic Crystal Fiber
Sensors, 2012 A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment of hollow-core photonic crystal fiber in ...
