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 ...

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.

Stabilized large mode area in tapered photonic crystal fiber for stable coupling [PDF]

, 2012
A rigorous modal solution approach based on the numerically efficient finite element method (FEM) has been used to design a tapered photonic crystal fiber with a large mode area that could be efficiently coupled to an optical fiber.

Three-dimensional femtosecond laser nanolithography of crystals [PDF]

, 2019
Nanostructuring hard optical crystals has so far been exclusively feasible at their surface, as stress induced crack formation and propagation has rendered high precision volume processes ineffective. We show that the inner chemical etching reactivity of
