体育场形介质腔准束缚波函数射线混沌特征
Signature of ray chaos in quasi-bound wave functions for a stadium-shaped dielectric cavity
摘要:
在光线模型和波动模型下研究了体育场形介质腔的光发射。对于低损耗的无源腔模,准束缚波函数的相空间表示与射线模型中的对应分布之间存在着显著的对应关系。这一结果提供了额外的和更直接的证据,良好的射线波对应的低损耗模式,以前观察到的远场发射模式比较的水平。
英文摘要:
Light emission from a dielectric cavity with a stadium shape is studied in both ray and wave models. For a passive cavity mode with low loss, a remarkable correspondence is found between the phase space representation of a quasi-bound wavefunction and its counterpart distribution in the ray model. This result provides additional and more direct evidence for good ray-wave correspondence in low-loss modes previously observed at the level of far-field emission pattern comparisons.
