This study investigates multimode semiconductor lasers with optical feedback, revealing how bifurcations lead to in-phase or antiphase dynamics. It explains low-frequency fluctuations as chaotic itinerancy among coexisting attractors.

Area of Science:

  • Nonlinear dynamics and chaos theory
  • Semiconductor laser physics
  • Optical feedback systems

Background:

  • Semiconductor lasers are crucial in modern optics and communications.
  • Optical feedback can significantly alter laser dynamics, leading to complex behaviors.
  • Understanding these dynamics is key to laser stability and applications.

Purpose of the Study:

  • To analyze the destabilization of steady-state operation in a multimode semiconductor laser under moderate optical feedback.
  • To investigate the role of Hopf and degenerate Hopf bifurcations in generating in-phase and antiphase dynamics.
  • To explain the origin of low-frequency fluctuations in the multimode regime.

Main Methods:

  • Bifurcation analysis of laser rate equations.

  • Numerical simulations of laser dynamics.
  • Characterization of coexisting attractors and chaotic itinerancy.

    • Main Results:

    • A simple Hopf bifurcation leads to in-phase dynamics.
    • A degenerate Hopf bifurcation results in antiphase dynamics and multiple coexisting attractors.
    • Low-frequency fluctuations are interpreted as chaotic itinerancy among unstable attractors.

    Conclusions:

    • Degenerate Hopf bifurcations are a key source of complex dynamics and multiple attractors in semiconductor lasers.
    • Chaotic itinerancy provides a framework for understanding low-frequency fluctuations in multimode lasers with optical feedback.
    • The findings offer insights into laser stability control and potential applications in chaos-based communication systems.
