Higher-order-compact time-domain numerical simulation of optical waveguides

摘要

Time-domain local-operator methods have proven valuable in simulating electromagnetic phenomena from DC to light with simple and complex media. Certain limitations do exist with the time-domain local-operator methods including wall-clock simulation times and cells per wavelength requirements. This work achieves lower simulation times through code optimizations, algorithm optimizations and parallelism. This yields faster simulations times and lower cell per wavelength requirements. The improved method has been applied to a set of optical problems.
