Abstract
Selective coupling to the fundamental mode of short hollow-core photonic bandgap fibres without exciting cladding modes is improved by gold-coated fibre end facets. Cladding modes are suppressed by 20–30 dB for single-and multimode fibre launch, respectively, while in-band power loss is 3–8 dB.
