On feasibility of longitudinal characterisation of photonic structures via transverse excitation of whispering gallery modes
On feasibility of longitudinal characterisation of photonic structures via transverse excitation of whispering gallery modes
Remote side excitation of whispering gallery modes (WGMs) in a photonic crystal fibre reveals longitudinal properties of its intra structure usually requiring a long propagation length and endface access. By tuning the excitation to maxima of observed morphology resonances, initiating axially expanding WGMs in the fibre cladding and in its microstructure, characteristic spectral windows resembling ones at the fibre longitudinal transmission are observed. This outcome opens up possibilities of remote characterisation of rotationally- symmetric photonic structures in situ and in locations only assessable via side excitation using external light beams.

Abstract
Remote side excitation of whispering gallery modes (WGMs) in a photonic crystal fibre reveals longitudinal properties of its intra structure usually requiring a long propagation length and endface access. By tuning the excitation to maxima of observed morphology resonances, initiating axially expanding WGMs in the fibre cladding and in its microstructure, characteristic spectral windows resembling ones at the fibre longitudinal transmission are observed. This outcome opens up possibilities of remote characterisation of rotationally- symmetric photonic structures in situ and in locations only assessable via side excitation using external light beams.
