Experimental observation of synchronization and anti-synchronization of chaotic low-frequency-fluctuations in external cavity semiconductor lasers

摘要

Experimental observations of synchronization and anti-synchronization of low-frequency-fluctuations of external cavity semiconductor lasers are presented. Antisynchronization occures not only for the well known power drop-out dynamic but also for the power jump-up dynamic. Detailed experimental investigations of the parameter space reveal several seperate areas of (anti-)synchronization. Numerical simulations with the Lang-Kobayashi model equations are presented for the antisynchronized power drop-out case.
