Mode degeneration in bent photonic crystal fiber study by using the finite element method [PDF]
, 2009 The development of highly dispersive lower and higher order cladding modes and their degeneration with respect to the fundamental core mode in a bent photonic crystal fiber is rigorously studied by use of the full-vectorial finite element method.

Dynamics simulation of photonic crystal fiber end face polishing
Advances in Mechanical Engineering, 2017 The high quality of polished end face of photonic crystal fiber has a significant effect on coupling efficiency when photonic crystal fiber is used to couple with other optical devices. In order to obtain the smooth surface of the photonic crystal fiber,

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

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.

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
