Packaging of surface nanoscale axial photonic microresonators

Due to their high Q factor and small volume surface, nanoscale axial photonic (SNAP) resonators have been used to study nonlinear effects, sensing, optomechanics and many other applications. The best way to couple light into SNAP resonators is through the evanescent field of a tapered fiber. However, these tapered fibers are fragile, and SNAPs are very sensitive to their environment. These factors make SNAP resonators difficult to to transport and keep intact for long periods of time without some kind of packaging. We present an inexpensive technique for packaging SNAP resonators as a pigtail device using a 3d printed housing and low index optical epoxy. We then report the effects of this packaging technique on the spectra and measure the change in spectra due to impact, heat and environmental impurities.
