The surface-plasmon-based spatial multiplexer studied in Figure 1 consists of a multiplexing switch that steers light toward one of several subwavelength metal-strip waveguides. The design parameters of the structure can also be perturbed in FullWAVE FDTD to allow the study of manufacturing tolerances on device performance. FullWAVE provides a full-vector solution to Maxwell’s equations and allows engineers to use complex material definitions, arbitrary device geometries, non-uniform grids, and sophisticated measurement techniques to create new plasmonic devices and fine-tune existing designs for specific applications. FullWAVE FDTD is the ideal tool to meet this need.
Simulating this effect requires a rigorous full-vector modeling environment that provides accurate solutions for arbitrary device geometries containing both metallic and nonmetallic components. One basic challenge facing the adoption of plasmon guides within electrical chips is the excitation of the plasmons from external sources. Routing the signals through surface-plasmon-based waveguides provides one possible way to achieve faster optical connection speeds these waveguides are compact, not bound by the diffraction limit, and can be easily integrated with both optical and electronic technologies. The speed of intra-chip and inter-chip connection is one of the main bottlenecks to achieving faster computer chip performance.

In this module, 2D FDTD solves the full set of time-dependent Maxwell’s equations by discretizing time using Courant–Friedrichs–Lewy condition to prevent divergence in the solution.
The 2D FDTD Simulations Module simulates fully time-dependent propagation in smaller structures. Designers can choose the simulation module that best suits their component design. OptoDesigner propagation simulation modules combine powerful simulations with next-generation design capabilities. OptoDesigner, part of the Synopsys PIC Design Suite, has photonic-aware physical layout capabilities to synthesize photonic integrated circuit (PIC) layouts for fabrication. For a wide range of integrated and nano-optic devices, FullWAVE has applications such as LED extraction analysis, diffractive optical element (DOE) design, PIC/Custom PDK element design, nanophotonics, and meta-materials design.
Its award-winning, innovative design and feature set has made FullWAVE the market leader among optical device simulation tools, with a cutting-edge implementation of a mature FDTD algorithm that allows for a wide range of simulation and analysis capabilities. Synopsys' FullWAVE simulation software, part of RSoft Photonic Device Tools, employs FDTD to perform a full-vector simulation of photonic structures. This effect is demonstrated, and its use to achieve a micron-sized waveguide switch is shown.Synopsys offers several photonic solutions tools that employ the FDTD method. By introducing further defects into the PBG waveguiding structures, control of the flow of electromagnetic energy in these nanometer-sized waveguides can be affected. Several waveguides and power dividers were designed and evaluated. Removal of particular portions of these PBG structures lead to interesting sub-micron-sized waveguiding environments.
