    Area of Science:

    • Optics and Photonics
    • Semiconductor Lasers

    Background:

    • Quantum cascade lasers (QCLs) are crucial for mid-infrared applications.
    • Achieving wide and stable tuning ranges in QCLs remains a challenge.

    Purpose of the Study:

    • To design and demonstrate a widely tunable single-mode quantum cascade laser array.
    • To explore the potential of slot waveguide structures for laser tuning.
    • To assess the device's suitability for mid-infrared sensing and spectroscopy.

    Main Methods:

    • Fabrication of a quantum cascade laser array utilizing slot waveguide structures.
    • Experimental characterization of the laser array's tuning range and mode stability.
    • Utilized current tuning at a constant temperature (300 K).

    Main Results:

    • Achieved a continuous tuning range of 71 cm-1 (9.66–10.37 μm) at 300 K.
    • Demonstrated stable single-mode operation without mode-hops across the tuning range.
    • Validated the design's universal applicability with a second array (41 cm-1 tuning range around 7.3 μm).

    Conclusions:

    • The developed slot waveguide quantum cascade laser array offers broad, continuous tuning.
    • Simple processing and wide tuning make it ideal for mid-infrared sensing and spectroscopy.
    • The design principle is broadly applicable to mid-infrared laser development.
