Abstract

We describe structure localization and dissipative solitons in a semiconductor laser with a saturable absorber exhibiting gain/absorption recovery times shorter than the photon lifetime. Under assumptions compatible with QCL characteristics and graphene-based absorbers, we study the existence and stability of solitons, along with their dynamical behavior. Numerical simulations confirm the robustness of our predictions. This evidence hints at promising pathways to realize passive mode locking in ultrafast lasers, implying highly valuable application prospects.

具有饱和吸收体的超快半导体激光器中的孤子

我们描述了具有饱和吸收体的半导体激光器中的结构局域化和耗散孤子，其增益/吸收恢复时间短于光子寿命。在与QCL特性和石墨烯基吸收体相容的假设下，研究了孤子的存在性、稳定性及其动力学行为。数值模拟证实了我们预测的稳健性。这一证据暗示了在超快激光中实现无源模式锁定的有希望的途径，具有很高的应用前景。
