S. Ebisawa, H. Miyazaki and S. Komatsu：Eavesdrop Detection for Chaotic Communication with Mutual Optical Coupling，Technical Digest, OSA Frontiers in Optics 2008 (Rochester, USA, October 2008)，JWA49.

We numerically study the characteristics of a mutual optical coupling system for chaotic communication., featuring the parameter sensitivity of the correlation between each laser output involving a certain time-lag, and discuss its applicability to eavesdrop detection.
