In this publication a new approach to simulate the mode dynamics in broad-ridge laser diode is presented. These devices exhibit rich lateral mode dynamics in addition to longitudinal mode dynamics observed in narrow-ridge laser diodes. The mode dynamics are strongly influenced by higher order effects, which are described by effective interaction terms and can derived from the band structure and the carrier scattering in the quantum well. The spatial dependency of pump current densities plays a crucial role in lateral mode dynamics, and thus, a Drift-Diffusion model is employed to calculate the current densities with an additional capturing term.

宽脊激光二极管的模式动力学仿真

在本出版物中，提出了一种模拟宽脊激光二极管模式动力学的新方法。除了在窄脊激光二极管中观察到的纵向模式动力学之外，这些器件还表现出丰富的横向模式动力学。模式动力学受到高阶效应的强烈影响，这些效应由有效相互作用项描述，并且可以从量子阱中的能带结构和载流子散射导出。泵浦电流密度的空间依赖性在横向模式动力学中起着至关重要的作用，因此，采用漂移扩散模型来计算带有附加捕获项的电流密度。
