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…

Optical transmittance degradation in tapered fibers
Masazumi Fujiwara, Kiyota Toubaru, Shigeki Takeuchi
We investigated the cause of optical transmittance degradation in tapered fibers. Degradation commences immediately after fabrication and it eventually reduces the transmittance to…
