Analytical mode normalization and resonant state expansion for optical fibers - an efficient tool to model transverse disorder

open access: yes, 2018
We adapt the resonant state expansion to optical fibers such as capillary and photonic crystal fibers. As a key requirement of the resonant state expansion and any related perturbative approach, we derive the correct analytical normalization for all ...

Optimized coupling of cold atoms into a fiber using a blue-detuned hollow-beam funnel

open access: yes, 2011
We theoretically investigate the process of coupling cold atoms into the core of a hollow-core photonic-crystal optical fiber using a blue-detuned Laguerre-Gaussian beam. In contrast to the use of a red-detuned Gaussian beam to couple the atoms, the blue-
