Abstract

Whispering gallery modes in birefringent crystalline resonators are investigated. We experimentally investigate the XY-cut resonators made with LiNbO3, LiTaO3, and BBO and observe strong influence of the resonator's shape and birefringence on the quality factor of the extraordinary polarized modes. We show that extraordinary modes can have lower Q and even be suppressed owing to polarization conversion loss. The ordinary ray modes retain the high Q due to inhibited reflection phenomenon.

摘要

我们研究了双折射晶体谐振器中的 whispering gallery 模式。我们实验研究了由 LiNbO3、LiTaO3 和 BBO 制成的 XY 切型谐振器，并观察到谐振器的形状和双折射对非寻常偏振模式的品质因数有很强的影响。我们表明，由于偏振转换损耗，非寻常模式的 Q 值可能较低甚至被抑制。由于抑制了反射现象，寻常光线模式保持了高 Q 值。
