Abstract

The recently demonstrated inductor-capacitor (LC) laser has a strongly subwavelength mode volume. In this Letter we investigate the Purcell effect in the LC laser resonator. An average Purcell factor of 17 is computed for the LC laser. The laser rate equations are formulated and solved for the LC laser. Evidence of a large Purcell factor in agreement with the theoretical one is obtained through comparison of the threshold and the emission characteristics of the LC laser with the rate equations.

摘要

最近展示的电感-电容 (LC) 激光具有强烈的亚波长模式体积。在这封信中，我们研究了 LC 激光谐振器中的 Purcell 效应。计算出 LC 激光的平均 Purcell 因子为 17。为 LC 激光制定了激光速率方程，并对其进行了解析。通过将 LC 激光的阈值和发射特性与速率方程进行比较，获得了与理论值相符的大 Purcell 因子的证据。
