Numerical Analysis on Chaos Synchronization in Semiconductor Lasers Subject to a Common Drive Signal

Abstract

We numerically observe chaos synchronization of two semiconductor lasers commonly driven by a chaotic semiconductor laser subject to optical feedback. We observe strongly correlated chaos synchronization between the two response lasers even when the correlation between the drive and response lasers is low. We show that the cross correlation between the two responses is larger than that between drive and responses over a wide parameter region.
