Monolithic temperature-insensitive high-<i>Q</i> Ta<sub>2</sub>O<sub>5</sub> microdisk resonator. [PDF]
NanophotonicsAbstract We demonstrate a temperature‐insensitive high‐Q tantalum oxide (Ta2O5) microdisk resonator fabricated using electron‐beam lithography and inductively coupled plasma reactive‐ion etching. The microdisks exhibit a loaded Q‐factor of 4.25 × 105 at 1,550 nm, which more than doubles (∼9.3 × 105) following thermal annealing at 600 °C.
