Hybrid Parallel Finite Difference Time Domain Simulation of Nanoscale Optical Phenomena

Abstract

The increasing computational demands of finite-difference time-domain simulations for studying optical phenomenon requires codes with very high performance. This paper introduces a new hybrid parallel code using standard MPI and OpenMP technologies. The code is portable to a variety of high performance systems. The transmission of light through an isolated sub-wavelength in an optically thick silver film is outlined as an example application of the code.
