Abstract

We discuss how optical nanofibers, subwavelength-diameter fibers, can open new perspectives in quantum optical technologies theoretically and experimentally. Discussions are mainly focused on the manipulation of spontaneous emission for atoms around the nanofiber. We show that photons from single quantum emitters can be efficiently channeled into guided modes of the nanofiber. Especially by fabricating a cavity structure of the nanofiber, the channeling efficiency can be improved to exceed 80% although the cavity finesse is moderate. We discuss also how to realize such a nanofiber cavity experimentally
