Multiscale optical simulation settings: challenging applications handled with an iterative ray-tracing FDTD interface method

摘要

We show that with an appropriate combination of two optical simulation techniques-classical ray-tracing and the finite difference time domain method-an optical device containing multiple diffractive and refractive optical elements can be accurately simulated in an iterative simulation approach. We compare the simulation results with experimental measurements of the device to discuss the applicability and accuracy of our iterative simulation procedure. (C) 2016 Optical Society of America
