Modeling photonic crystal fibers
Advances in Applied Mathematics, 2006 AbstractWe study guidance of electromagnetic waves in photonic fibers. Both transverse magnetic and transverse electric polarizations are investigated. We characterize guided modes in the fiber as eigenfunctions of compact integral operators and prove their exponential decay in the cladding.

Leakage properties of photonic crystal fibers
Optics Express, 2002 An analysis of the con.nement losses in photonic crystal fibers due to the finite numbers of air holes is performed by means of the finite element method. The high flexibility of the numerical method allows us to consider fibers with regular lattices, like the triangular and the honeycomb ones, and circular holes, but also fibers with more complicated ...

Avoided crossings in photonic crystal fibers
Optics Express, 2011 The impact of avoided crossings (also known as anti-crossings) in single and double-clad large mode area Photonic Crystal Fibers (PCFs) suitable for high-power laser systems is evaluated numerically. It is pointed out that an inappropriate choice of pump core diameter, bending radius and/or index depression may lead to avoided crossings that manifest ...
