Polarization-resolved cross-correlated (C2) imaging of a photonic bandgap fiber

Journal article, 2016

We demonstrate polarization-resolved frequency domain cross-correlated (C2) imaging to characterize a 5m length of hollow-core photonic bandgap fiber. We produce a spectrogram of the fiber response to investigate the spatial, polarization, spectral, and temporal behavior. We then show how this temporally-resolved technique can be used to characterize multiple fiber launch conditions simultaneously by assigning each a unique time delay.
