For solving opto-electronic problems modified with modern plasmonic structures as performance enhancers, we need to find carrier generation due to optical excitation. FDTD is the most suitable method used for finding optical response of devices with sub wavelength dimensions. Above listed commercial software have their own capabilities as well as limitations. Electromagnetic solver of Synopsis TCAD has lot of limitations in terms of geometry of structures. for example, it is very difficult to get converged simulations when metallic structures with sub wavelength holes. Inserting model parameters is a tedious job. Where as Lumerical FDTD has been very popular for solving this kind of problems very easily but incapable of solving electrical response of semiconductors. In this regard, if there is any simple ways to couple both these tools , it will be very helpful to reduce time of simulations and increase the accuracy.
Synopsys acquired RSoft (the first photonics simulation company) in 2012 and have integrated RSoft products into Sentaurus WorkBench, seamlessly. In addition to FDTD (package called FullWAVE), other efficient optical solvers, such as BPM (package called BeamPROP) can also be used.
