Abstract:
Wavelet transform analysis of experimentally measured intensity fluctuations distinguishes the transition from low frequency fluctuations at moderate feedback to stable operation at strong feedback. Comparison of these results with those of a wavelet analysis of lowpass filtered solutions of the Lang-Kobayashi equations for deterministic evolution of a single mode semiconductor laser with optical feedback finds substantial agreement in the part of the wavelet spectrum corresponding to slow dynamics. Substantial disagreement is found in the fast dynamics, which lessens when noise is added to the equations. © 1998 Elsevier Science B.V. All rights reserved.
