提出了一种波纹节距调制相移分布反馈（DFB）激光器，以减小沿激光腔的空间孔燃烧效应。给出了所提出的波纹节距调制相移DFB激光器的结构。从其作为驱动电流函数的光谱行为可以证实这种效应的减小。因此，稳定的单纵向模式的工作，直到高输出功率获得
A corrugation-pitch-modulated phase-shifted distributed feedback (DFB) laser is proposed to reduce the spatial-hole-burning effect along the laser cavity. The structure of the proposed corrugation-pitch-modulated phase-shifted DFB laser is illustrated. A reduction in this effect is confirmed from its spectral behavior as a function of driving current. Consequently, stable single-longitudinal-mode operation up to high-output powers is obtained.>
