Numerical simulations of single whispering-gallery mode enhancement in hollow cylindrical optical microcavity [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 In this work, a hollow cylindrical optical microcavity is numerically investigated by finite-difference time-domain simulations. Enhancement of a single whispering-gallery mode (WGM) is realized by inserting a periodic hole array into the hollow ...

Mechanical quality factor of a sapphire fiber at cryogenic temperatures [PDF]
, 2000 A mechanical quality factor of $1.1 \times 10^{7}$ was obtained for the 199 Hz bending vibrational mode in a monocrystalline sapphire fiber at 6 K. Consequently, we confirm that pendulum thermal noise of cryogenic mirrors used for gravitational wave ...
