    Area of Science:

    • Optics and Photonics
    • Laser Physics
    • Materials Science

    Background:

    • Compact fiber lasers are vital for sensing, communications, and medicine.
    • Distributed feedback (DFB) rare-earth doped fiber lasers with phase-shifted Bragg gratings offer significant potential.

    Purpose of the Study:

    • To theoretically analyze complex-frequency modes of DFB fiber laser cavities.
    • To determine the optimal defect position in Bragg gratings for maximizing one-sided output power.

    Main Methods:

    • Complex-frequency analysis of open cavity response function poles.
    • Application of laser rate equations.
    • Investigating the influence of pump power on defect position.

    Main Results:

    • An optimal defect position was identified to maximize one-sided output power.
    • The optimal defect position is dependent on pump power.
    • Near threshold, a central defect is optimal; at higher pumping, an asymmetric position is favored.

    Conclusions:

    • Specific variables were identified for determining optimal defect positions in diverse DFB laser configurations.
    • This research provides a method for enhancing the performance of DFB fiber lasers.
