Ultrathin fiber-taper coupling with nitrogen vacancy centers in nanodiamonds at cryogenic temperatures
Masazumi Fujiwara, Hong-Quan Zhao, Tetsuya Noda +3
We demonstrate cooling of ultrathin fiber tapers coupled with nitrogen vacancy (NV) centers in nanodiamonds to cryogenic temperatures. Nanodiamonds containing multiple NV centers a…
Coupling of ultrathin tapered fibers with high-Q microsphere resonators at cryogenic temperatures and observation of phase-shift transition from undercoupling to overcoupling
Masazumi Fujiwara, Tetsuya Noda, Akira Tanaka +3
We cooled ultrathin tapered fibers to cryogenic temperatures and controllably coupled them with high-Q microsphere resonators at a wavelength close to the optical transition of dia…
Highly efficient coupling of photons from nanoemitters into single-mode optical fibers
Masazumi Fujiwara, Kiyota Toubaru, Tetsuya Noda +2
Highly efficient coupling of photons from nanoemitters into single-mode optical fibers is demonstrated using tapered fibers. 7.4 +/- 1.2 % of the total emitted photons from single…
