A dual-region ytterbium tweezer apparatus with an in-vacuum nanofiber cavity
Shunichiro Hashimoto, Hideki Ozawa, Yusuke Hisai +2
We present a dual-region experimental apparatus for trapping single atoms of the fermionic isotope ytterbium-171 () with optical tweezers in a science chamber…
Strong coupling of a reconfigurable Yb atom array to a tunable telecom-band nanofiber cavity
Hideki Ozawa, Neville Chen, Yusuke Hisai +13
Nanophotonic cavities provide strong atom-photon coupling in a compact, directly fiber-coupled geometry, while a reconfigurable array of Yb atoms combines high-fidelity gat…
Reduction of hydroxyl groups in optical nanofibers via in-fiber laser heating
Koki Oguri, Ken-ichi Harada, Samuel K. Ruddell +2
Optical nanofibers fabricated using a standard oxyhydrogen flame exhibit optical losses at wavelengths around 1385~nm due to absorption by embedded hydroxyl groups, posing a challe…
Fabrication of high-Q defect-free optical nanofiber photonic crystal resonators
Tomofumi Tanaka, Takahiro Suzuki, Owen Mao +3
We demonstrate the fabrication of defect-free optical-nanofiber photonic-crystal Fabry-Perot resonators with quality factors exceeding 10^7 using single-shot femtosecond laser abla…
