N2 - Electrodispensing is a technique that can be used to precisely fabricate tunable microspheroids, of various shapes and sizes. Recent investigations have demonstrated their use as solid immersion lenses (SIL’s), with large numerical apertures, and short focal lengths; this makes them perfect for coupling light into and out of semiconductor devices. Furthermore fabricating SIL’s from UV cure epoxy has significant advantages over conventional glass formed SIL’s, allowing their size, location and shape to be perfectly tuned to the individual requirements of the system, greatly increasing the extraction efficiency and resolution, a boon to many optoelectronic applications. GaSb Quantum rings (QR) provide strong zero-dimensional confinement, which may make them suitable as quantum light sources at telecoms wavelengths. However, when these nanostructures are embedded in a semiconductor structure most of the light emitted by them is lost to total internal reflection. Here we show that electrodispensed UV-cured SIL’s can be deterministically coupled to quantum rings to massively increase the output coupling efficiency of these structures. This promises a simple and cheap solution to the development of useful quantum light sources.
