| Research Abstract |
An implicit FDTD method based on the locally one-dimensional (LOD) scheme has been developed for the efficient analysis of three-dimensional (3-D) plasmonic devices. The trapezoidal recursive convolution technique has been adopted, in which a single convolution integral is required. In addition, a fundamental scheme has been introduced for efficient formulation of the algorithm, in which no spatial derivative exists in the right-hand side of the equations. The developed LOD-FDTD offers a reduced computation time from 85 min with the conventional explicit FDTD to 37 min for the analysis of a plasmonic gap waveguide. The characteristics of several 3-D plasmonic devices have been investigated using the LOD-FDTD. The 3-D results have been compared with those of 2-D models, showing the necessity of the 3-D analysis for an accurate evaluation of the plasmonic devices.
