Abstract-The three-dimensional (3-D) beam-propagation method is applied to the analysis of a novel transverse electric/ transverse magnetic (TE/TM) wave splitter using a light-guiding metal (Ag) line with an embedded dielectric (SiO 2 ) 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 (> 1000 µm), the present splitter is found to have a noticeably short device length of less than 200 µm, 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 1.31 and 1.55 µm.Index Terms-Beam-propagation method (BPM), light-guiding metal line, mode converter, surface plasmon polaritons (SPP), TE/TM wave splitter.

“…All variants of integrated optics based polarization splitters rely on the waveguide birefringence phenomenon [69]. There are different implementations of the splitter in the literature such as; birefringent directional couplers [70,71], asymmetric Y junctions [72][73][74], interference based birefringent splitters [75,76], grating based devices [77][78][79] and photonic crystal based devices [80].…”

A novel intersection waveguide-type polarization splitter based on total reflection using the birefringence of the GaInAsPhP superlattice waveguide is proposed and analyzed in this paper. The semivectorial finite difference beam propagation method (FD-BPM) (which handles both TE and TM modes) is used in the analysis. The waveguide structure including the GaInAsP/InP superlattice is designed; and it is shown that, although with a superlattice core the refractive index for the TM mode is reduced by approximately 0.4 percent, there is no change for the TE mode. Based on this result, the optimal structural parameters such as superlattice layer number, rib height (h), intersecting angle (O), and port separation length (Lsp) are investigated using a 1.55-pm wavelength. It is found that the TE and TM modes can be separated with an insertion loss of less than 0.4 dB for both modes and a crosstalk of less than -35 dB using an intersecting angle of 5" and a device length of approximately 0.9 mm. It is shown that compared to conventional devices, the device length in the proposed device structure can be reduced by using total reflection. The wavelength dependence of the device is also analyzed. . He was a Researcher at Bath University in England between 1981 and 1983. He has been engaged in research on optical waveguides, optical integrated circuits, optical amplifiers, and quantum well devices. Dr. Kambayashi is a member of the IEEE and the Japan Society of Applied Physics.Kazuyuki Nakasendou graduated in 1993 from the Department of Electrical Engineering, Nagaoka University of Technology, where he received his M.S. degree in 1995.
