Direct Modulation Bandwidth Improvement in Two-section DFB Lasers Based on the Detuned Loading Effect

Yifan Xu et al.

Summary: A directly modulated two-section distributed feedback semiconductor laser is proposed and investigated. The detuning of the gratings in the two sections is achieved using the reconstruction-equivalent-chirp technique, resulting in improved modulation bandwidth. The device has potential applications in optical communications and microwave photonics.

Improvement on Direct Modulation Responses and Stability by Partially Corrugated Gratings Based DFB Lasers With Passive Feedback

Siti Sulikhah et al.

Summary: DFB lasers with partial corrugated gratings and passive feedback are proposed to address the challenges of directly modulated lasers. By designing a specific structure, high single-mode yield is maintained while improving modulation response and reducing waveform distortions. These lasers offer robustness in applying integrated passive reflectors for reshaping modulation response and enhancing bandwidth.
