    Variations in mirror reflectivity in coupled waveguided resonators can suppress specific laser modes. This coupling effect influences the threshold gain, impacting overall device performance.

    Area of Science:

    • Photonics
    • Optical Engineering
    • Quantum Optics

    Background:

    • Laterally coupled waveguided resonators are fundamental in integrated optics.
    • Understanding mode behavior is crucial for laser design and performance optimization.

    Purpose of the Study:

    • To analyze the longitudinal modes of coupled waveguided resonators.
    • To investigate the impact of asymmetric mirror reflectivity on mode coupling and suppression.

    Main Methods:

    • Longitudinal-mode analysis using the coupled-mode approximation.
    • Theoretical modeling of optical resonator systems.

    Main Results:

    • Mirror reflectivity variations induce coupling between supermodes.
    • This coupling can lead to the suppression of specific Fabry-Perot modes.
