摘要:

提出并演示了一种用于激光器阵列的新型光栅调制技术。该方法在每个光栅周期内修改初始相位,施加按等差级数递增的总相移,从而确保阵列中各通道间隔相等。尽管相移各不相同,该器件仍保持与传统均匀光栅结构相当的耦合效率。此外,连续相位调制增强了主模激射波长的稳定性,降低了对制造误差的敏感性。这种对制造偏差容忍度的提高代表了一项重要的技术进步,使该方法在需要精确且稳定波长控制的应用中极具前景。

英文摘要:

A novel grating modulation technique for laser arrays is proposed and demonstrated. This method modifies the initial phase within each grating period, applying a total phase shift that increments in an arithmetic progression, ensuring equal channel spacing across the array. Despite the varying phase shifts, the device maintains coupling efficiency comparable to traditional uniform grating structures. Furthermore, the continuous phase modulation enhances the stability of the lasing wavelength of the primary mode, reducing sensitivity to fabrication errors. This improved tolerance to manufacturing inaccuracies represents a significant technological advancement, making this approach highly promising for applications requiring precise and stable wavelength control.
