FDTD-SUPML simulation of photonic integrated circuits
Accurate modeling of photonic integrated circuits (PIC) is essential for development of high performance optical components. In this work, a finite difference time domain method (FDTD), combined with a simplified uniaxial perfectly matched layer boundary condition is presented to efficiently analyze light propagation in PIC. The FDTD-SUPML formulation can be easily applied to complex optical components. Numerical examples illustrate that this combined approach gives high accuracy.
