title: Experimental demonstration of the frequency shift of bandgaps in photonic crystal fibers due to refractive index scaling.
abstract: Experimental demonstration of the frequency shift of photonic bandgaps due to refractive index scaling using D2O-filled hollow-core photonic crystal fibers is presented. The results confirm a simple scaling law for bandgaps in fibers in which the low-index medium is varied.
