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.
