Theory of two-dimensional microcavity lasers

- T. Harayama, S. Sunada, K. Ikeda
- Physics
- 6 July 2005

We present theoretical models of two-dimensional (2D) microcavity lasers. The relation between stationary lasing modes and resonances or metastable states is elucidated for arbitrary shapes of 2D… Expand

Chaotic tunneling: a remarkable manifestation of complex classical dynamics in non-integrable quantum phenomena

Abstract The tunneling phenomenon in chaotic systems is analyzed in terms of the complex semi-classical method in the time domain. In contrast to the tunneling paths in integrable systems, it is… Expand
