微腔中的光学共振可以通过光学或热来操纵。利用热导体控制热耗散，实现了对不同尺寸二氧化硅微腔中光学共振的调谐。有限元热分析表明，微腔模式体积中的温度可以确定地调节，并且共振在<；内联公式&><；$1.55~\MU\Text{m}$<；/内联公式&>$1.55~\MU\Tex-Math>；附近的共振位移在~160-；内联公式&>；<；内嵌-数学符号=“LaTeX”>；$\MU\Text{m}$<；<；/内联公式>；-直径型腔。此外，还从单模布里渊激光的输出中间接地研究了直列公式=“LaTeX”>；$\MUT{m}$<；/tex-math>；<；/inline-formula>；-diameter腔中的微小共振漂移。与光学耦合相比，热相互作用空间要大得多，满足了以稳健的方式操纵高质量共振的需要。
Optical resonances in a microcavity can be optically or thermally manipulated. Here, the tunings on optical resonances in silica microcavities with various dimensions are achieved by controlling the thermal dissipation with a thermal conductor. Finite-element thermal analyses show that the temperature in a mode volume of a microcavity can be definitely tuned, and the shifts of resonances near <inline-formula> <tex-math notation="LaTeX">$1.55~\mu \text{m}$ </tex-math></inline-formula> are verified experimentally in a ~160-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>-diameter cavity. In addition, the slight resonance shifts in a ~450-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>-diameter cavity are examined indirectly from the output of single-mode Brillouin lasing. Compared to that of optical coupling, the thermal interaction space is much larger and fulfills a need to manipulate the high-quality resonances in a robust way.
