Abstract

An analytical expression was derived for light amplification by stimulated emission in arbitrary photonic crystals, which showed and enhancement due to small group velocity. This enhancement was evaluated quantitatively for a two-dimensional crystal with a finite thickness, and an extremely large enhancement due to group-velocity anomaly peculiar to two- and three-dimensional crystals was found even for quite a thin crystal.

摘要

推导了任意光子晶体中受激辐射光放大的解析表达式，该表达式表明由于群速度小而实现了增强。对具有有限厚度的二维晶体进行了定量评估，结果发现，即使是相当薄的晶体，由于二维和三维晶体特有的群速度异常，也会出现极大的增强。
