摘要：

<正>With the significant expansion of communication capacity in fiber-optic networks, the directly modulated laser serves as a viable candidate due to its low cost and small footprint. In recent years, distributed feedback(DFB)lasers with an integrated passive feedback waveguide were demonstrated to enhance bandwidth by introducing a photon–photon resonance or detuned-loading effect. However, the butt-joint regrowth process between the active layer and passive waveguide complicates the fabrication. Here we propose and demonstrate a DFB laser with an integrated active feedback waveguide, utilizing identical active layer technology to simplify the fabrication process, achieving a bandwidth of exceeding 50 GHz. Additionally, transmission experiments with 55 Gbps NRZ and70 Gbps PAM4 signals are also demonstrated. ? 2024 Chinese Laser Press
