4 December 1998 Enhanced stimulated emission in a two-dimensional photonic crystal
Author Affiliations +
An analytical expression is presented for light amplification by stimulated emission in arbitrary photonic crystals, which shows an enhancement due to small group velocity. This enhancement was evaluated quantitatively for a 2D crystal with a finite thickness composed of a square array of circular air-rods formed in a dielectric material. In addition to the enhancement at photonic band edges where the group velocity is equal to zero, an extremely large enhancement due to the group-velocity anomaly peculiar to 2- and 3-D crystals was found even for quite a thin structure.
