This Letter presents a method for the fast and broad wavelength sweeping of a standard setup of a diode's active region and its immediate vicinity, which contain the diode's optical feedback system. The selective and rapid heating of the active region is possible due to the confinement of the voltage drop to the active diode's region that has submicrometer thickness. Using the presented method and an off-the-shelf telecommunication distributed feedback laser diode, we demonstrate wavelength sweeps in excess of 10 nm that were completed in about 200 ns, while generating average optical power in excess of 50 mW. In spite of high-amplitude current-drive pulses, 6000 h continuous operation of the diode within such an operational regime did not show any significant degradation of the diode's performance.
这封信提出了一种快速、宽波长扫描二极管有源区及其紧邻区域（包含二极管光学反馈系统）的方法。由于电压降局限在厚度小于亚微米的有源二极管区域，因此可以对有源区域进行选择性和快速加热。使用所提出的方法和现成的电信分布式反馈激光二极管，我们展示了超过 10nm 的波长扫描，这些扫描在大约 200ns 内完成，同时产生超过 50mW 的平均光功率。尽管有高幅度电流驱动脉冲，但在这种工作模式下，该二极管连续运行 6000 小时，其性能没有出现任何显著下降。
