Abstract

On-chip hollow-core waveguides represent a promising platform for microfluidic analysis, nonlinear optics and quantum information processing, due to light guidance directly inside the medium of interest. Recently, we have reported a 3D printed hollow-core waveguide ⎯ light cage ⎯ which consists of a ring of high-aspect-ratio cylinders and combines a high fraction of field in the core (>99%) with transverse access. Here we will discuss our results on interfacing light cages with optical fibers, the measurement of electromagnetically induced transparency within light cages filled with alkali vapour, the potential of the light cage concept for spectroscopy and nanoparticle tracking analysis.
