| Abstract(in English) | The three-dimensional beam-propagation method is applied to the analysis of a novel TE/TM wave splitter using a light-guiding metal line with an embedded dielectric waveguide. Before analyzing the splitter, a mode converter with a tapered metal is designed to smoothly convert the guided mode of an embedded waveguide into the surface plasmon polariton (SPP) mode and vice versa. After demonstrating the effectiveness of a converter consisting of a two-step linear taper, the performance of the splitter is evaluated. To obtain a high coupling efficiency, the wavefront mismatch of the SPP mode is compensated for. In addition, a TE-pass polarizer is added to the TE output waveguide, reducing the undesirable TM wave. In contrast to the long device length of a conventional branch-type splitter (> 1000μm), the present splitter is found to have a noticeably short device length of less than 200μm, although a loss of about 3 dB is observed for the TM wave. The crosstalk and the extinction ratio are, respectively, evaluated to be less than -15 dB and more than 15 dB for a branching angle of 16±2°at wavelengths of 1.31μm and 1.55μm. |
