利用高色散材料提高微腔寿命
Enhancement of microcavity lifetimes using highly dispersive materials
摘要：
我们分析，数值计算表明，高色散介质可以用来大幅增加高Q值微谐振器的寿命。在这样的谐振器中，寿命受到不期望的与辐射的耦合或组成材料的固有吸收的限制。色散的存在减弱了与不期望的辐射模式的耦合，并且还有效地降低了材料吸收。
英文摘要：
We show analytically, and numerically that highly-dispersive media can be used to drastically increase lifetimes of high-Q microresonators. In such a resonator, lifetime is limited either by undesired coupling to radiation, or by intrinsic absorption of the constituent materials. The presence of dispersion weakens coupling to the undesired radiation modes and also effectively reduces the material absorption.
