In this work, the influence of strong optical feedback on the emission behavior of distributed Bragg-reflector ridge waveguide diode lasers emitting at 1120 nm with different cavity lengths and facet reflectivities is investigated. Based on measurements of the optical output power, central emission wavelength, and spectral emission width, the different diode laser types are compared while optical feedback up to -8 is applied. The observed changes of the optical output power and emission wavelength as well as the occurrence of coherence collapse states give insight into the resistance against feedback of the different diode laser types.
在这项工作中，研究了强光学反馈对不同腔长和端面反射率的1120nm分布式布拉格反射器脊形波导二极管激光器发射行为的影响。基于对光输出功率、中心发射波长和光谱发射宽度的测量，在施加高达-8的光学反馈时，对不同类型的二极管激光器进行了比较。观察到的光输出功率和发射波长的变化以及相干崩溃状态的出现，有助于深入了解不同类型二极管激光器对反馈的抗性。
