2004/8/11
It is known that the coupling of core modes to surface modes in air-core photonic-bandgap fiber (PBF) can give rise to large propagation losses. Using computer simulations, we analyze the relationship...
Simulations of the effect of the core ring on surface and air-core modes in photonic bandgap fibers
