本文提出了一种对二极管有源区及其邻近区域的标准设置进行快速宽波长扫描的方法，其中包含二极管的光反馈系统。由于压降被限制在具有亚微米厚度的有源二极管的区域，因此有源区的选择性和快速加热是可能的。利用所提出的方法和一个现成的通信分布反馈激光二极管，我们实现了波长超过10 nm的扫描，在产生平均光功率超过50 mW的同时，大约在200 ns内完成了扫描。尽管有高幅度的电流驱动脉冲，二极管在这样的工作状态下连续工作6000h并没有显示出二极管性能的任何显著下降。(C)2013年美国光学学会
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.
