Effective area of photonic crystal fibers [PDF]
, 2002 We consider the effective area A_eff of photonic crystal fibers (PCFs) with a triangular air-hole lattice in the cladding. It is first of all an important quantity in the context of non-linearities, but it also has connections to leakage loss, macro ...

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

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.

Fabrication Long Period Fiber Bragg Grating Based on Photonic Crystal Fiber Using CO2 Laser
مجلة النهرين للعلوم الهندسيةPhotonic crystal fibers (PCFs) are generally divided into two categories: solid-core photonic crystal fibers and hollow-core photonic crystal fibers. In this paper, a long-period fiber Bragg grating (LPFBG) was experimentally fabricated in a hollow-core
