    Area of Science:

    • Semiconductor Lasers
    • Infrared Photonics
    • Materials Science

    Background:

    • Interband cascade lasers (ICLs) are crucial for mid-infrared applications.
    • Achieving high-quality surface gratings and stable single-mode operation in ICLs remains a challenge.
    • Distributed feedback (DFB) mechanisms are essential for wavelength control and single-mode emission.

    Purpose of the Study:

    • To design, grow, and fabricate a second-order distributed feedback interband cascade laser (DFB-ICL) emitting at 3.25 µm.
    • To investigate the use of a GaSb cap layer for improved surface grating quality.
    • To evaluate the laser's performance in terms of threshold current, output power, tuning range, and single-mode stability.

    Main Methods:

    • Coherent epitaxy of a GaSb cap layer on the laser structure.
    • Fabrication of a second-order surface grating using GaSb and gold.
    • Design and simulation using couple-wave theory.
    • Device fabrication with 2-mm-long cavities and 4.5-µm-wide ridges.
    • Characterization of continuous-wave (CW) performance at various temperatures.

    Main Results:

    • A high-quality GaSb/gold surface grating was successfully fabricated.
    • Simulations predicted sufficient coupling strength and inter-modal loss difference.
    • The fabricated DFB-ICL exhibited a CW threshold current of 60 mA and a maximum output power of 24 mW at 20°C.
    • Stable single-mode operation with high side-mode suppression ratios (>20 dB) was achieved over a tuning range of >20 cm⁻¹.
    • Output power remained at 5 mW even at 55°C.

    Conclusions:

    • The novel GaSb cap epitaxy approach enables high-quality surface gratings for DFB-ICLs.
    • The fabricated 3.25 µm DFB-ICL demonstrates excellent performance, including stable single-mode emission and broad continuous tuning.
    • This work contributes to the development of advanced mid-infrared laser sources for various applications.
