Abstract

An experiment was conducted to provide evidence of low-frequency limit cycles and chaos in semiconductor lasers with single mirror external feedback. The coupled cavity configuration consists of a Toshiba InGaAlP semiconductor laser emitting at 693 nm. The optical output signals were detected using a fast photodiode through a 50% beam splitter and analyzed using a 2 GHz Lecroy digital oscilloscope. The correlation dimension for the chaotic time series after nonlinear noise reduction was calculated to characterize the dynamics. Results show that chaos is low-dimensional for nearly single-mode and high-dimensional for multi-mode operations, indicating a reduced dynamical complexity.
