摘要

本文报道了利用三维DTEQM-FDTD对半导体光子器件进行建模的方法。该模型包括泡利不相容原理、费米-狄拉克热化和状态填充等物理特性,描述了半导体介质中复杂的电子动力学,充分发挥了时域有限差分的潜力。该模型演示了载流子带内和带间跃迁动力学、能带填充和热平衡。DTEQM-FDTD模型既包含了复杂动态介质的基本物理特性,又具有计算效率。通过采用适当的速率方程和能级结构,它适用于广泛的原子和分子介质。

3D modeling of photonic devices using dynamic thermal electron quantum medium finite-different time-domain (DTEQM-FDTD) method
This paper reports on the modeling of the semiconductor photonic devices using 3D DTEQM-FDTD. The model includes the physics of Pauli Exclusion principle, Fermi-Dirac thermalization and state filling to describe the complex electron dynamics in semiconductor media to realize the full potential of FDTD. The carrier intraband and interband transition dynamics, energy band filling and thermal equilibrium are demonstrated in the model. The DTEQM-FDTD model includes the essential physics of complex dynamical media and yet computational efficient. It is applicable to a wide range of atomic and molecular media by applying the appropriate rate equations and energy level structure.
