Abstract
Nanofiber-based optical cavities enable the creation of devices with strong atom-photon coupling; the cavity can be obtained by milling Bragg mirrors on a nanofiber. Here, we present experimental progress to optimize the quality of a triplex air-nanocube structured nanofiber cavity. The structures are produced by focused Ga+ ion beam milling. The quality factor obtained was ∼784 in a periodic structure of only 20 mirrors and structures with up to 50 mirrors were fabricated to increase the quality factor. Subsequently, single quantum emitters, such as quantum dots, deposited onto the cavity should achieve strong coupling. The proposed nanofiber-based cavity creates a small, integrated device for the study of single quantum emitters for quantum networks.
