     View Summary

    © 2015 OSA. We introduce nanofiber Bragg cavities fulfilling three important requirements: small mode-volume, wide tuning-range, and efficient fiber-coupling. In a first application, we show enhancement of single quantum emitters such as quantum dots and nitrogen vacancy centers.
