Microstructured optical fibers: where�??s the edge?

Optics Express, 2002
We establish that Microstructured Optical Fibers (MOFs) have a fundamental mode cutoff, marking the transition between modal confinement and non-confinement, and give insight into the nature of this transition through two asymptotic models that provide a mapping to conventional fibers.

Design of Environmental Biosensor Based on Photonic Crystal Fiber with Bends Using Finite Element Method [PDF]

, 2015
In this paper, a biosensor based on photonic crystal fiber (PCF) is proposed and designed using Full-Vectorial Finite Element Method (FVFEM). The proposed PCF sensor consists of three concentric circles surrounding the core.

Fabrication of multiple parallel suspended-core optical fibers by sheet-stacking [PDF]

, 2014
We demonstrate the fabrication of a novel type of optical fibers with multiple parallel air-suspended cores by the sheet-stacking method. Using this technique we have constructed optical fibers with up to 10 parallel micron-size suspended cores. No extra

High-power supercontinuum generation with picosecond pulses [PDF]

, 2010
We investigate both theoretically and experimentally the properties of supercontinuum generation in the nearinfrared and visible regimes using high-power picosecond pulses propagating in a photonic crystal optical fiber. We discuss the effect of the pump
