Optical feedback causes instabilities in quantum dot semiconductor lasers. This leads to power fluctuations between ground and excited states, maintaining constant total output power.

Area of Science:

  • Quantum optics
  • Semiconductor device physics
  • Laser dynamics

Background:

  • Quantum dot semiconductor lasers operate in both ground and excited states.
  • These devices can exhibit antiphase fluctuations without external influences.
  • Understanding laser stability is crucial for device applications.

Purpose of the Study:

  • To investigate feedback-induced instabilities in quantum dot semiconductor lasers.
  • To analyze the dynamic behavior of ground and excited states under optical feedback.
  • To determine the effect of feedback on total output power.

Main Methods:

  • Experimental study of a quantum dot semiconductor laser.
  • Analysis of laser dynamics with and without optical feedback.

  • Measurement of power fluctuations in ground and excited states.

    • Main Results:

    • Without optical feedback, antiphase fluctuations occur between ground and excited states, with constant total output power.
    • Optical feedback induces power dropouts in the ground state.
    • Optical feedback causes intensity bursts in the excited state, maintaining constant total output power.

    Conclusions:

    • Optical feedback significantly alters the dynamic behavior of quantum dot semiconductor lasers.
    • The observed power dropouts and bursts maintain overall power stability.
    • These findings are important for controlling and optimizing laser performance.
