OptiFDTD provides comprehensive post-simulation analysis tools. Such as transmittance spectrum analysis, mode overlap calculation, input overlap calculation, far field calculation, Poynting vector analysis, polarized power calculation and so on. These analysis tools were mainly used in the analyzer. Some users may want to perform the sweep simulation and want feedback the results to the layout designer so that the layout can be optimized, or some users may want to get the power transmission/reflection spectrum results without the manipulation of opening the analyzer.

Access to the simulation result data of Observation Objects is a critical feature needed for optimization of the designed devices. Exposure of the available data through the VBScript interface allows for implementation of the basic optimization algorithms within the script and provides the means to access third party solutions supporting COM Automation
