在这项工作中，我们比较了超短脉冲产生在单片两段二极管激光器芯片的基础上被动和自锁模（PML和SML）制度在1550 nm。在PML中，我们向增益段施加正向电流，向吸收段施加反向电压。对于SML操作，通过施加正向电流来操作两个段。在这两种情况下都得到了自相关宽度约为7-8皮秒的强啁啾脉冲。我们分析了基于光纤的脉冲宽度压缩到亚皮秒范围的潜力。
In this work, we compare ultrashort pulse generation in a monolithic two-section diode laser chip based on passive- and self- mode-locking (PML and SML) regimes at 1550 nm. In PML, we apply a forward current into the gain segment and a reverse voltage into the absorber segment. For SML operation, both segments are operated by applying a forward current. Strongly chirped pulses with an autocorrelation-width of roughly 7-8 picoseconds are obtained for both cases. We analyze the potential for fiber-based compression of the pulse widths down to the sub-picosecond range.
