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…

Prevention of Yb adsorption by paraffin coating
Kanta Asakawa, Taichi Kobayashi, Masami Yasuda +2
Ytterbium (Yb) is used in cold-atom systems, including magneto-optical traps and optical lattice clocks. However, the long-term operation of such systems may be associated with sub…

A low-loss telecom-band nanofiber cavity for interfacing Yb atomic qubits
Seitaro Horikawa, Shinya Kato, Ryotaro Inoue +3
We demonstrate the fabrication of an optical nanofiber cavity designed for efficient interface with ytterbium (Yb) atoms at telecom-wavelength transitions. Replacing the convention…
