We fabricated optical microfiber knot resonators from thin tapered fibers (diameter down to 1 mu m) linked to untapered fiber at both ends. We demonstrated a finesse of about 100, over twice as high as previously reported for microfiber resonators. Low-loss encapsulation of microfiber knot resonators in hydrophobic silica aerogel was also investigated.
