Proposal of an Ultra-Compact Branch-Type Plasmonic Polarization Beam Splitter (PBS)

Abstract—Branch-type polarization beam splitter (PBS) has not been received much attention recently due to its relatively long device-length (~100s µm). In this paper, we proposed a novel design based on the horizontal nanoplasmonic slot waveguide to address this problem. A detailed design principle and procedures to optimize the device parameters are clearly illustrated. Comprehensive numerical analysis is performed to investigate the performance of the devices using the finite-difference time-domain (FDTD) methods. By carefully designing the widths of the branches, we shows that more than 15dB extinction ratio can be achieved, using only 1μm active device length. Proof-of-concept devices are subsequently fabricated in a CMOS-compatible process and characterized, producing results that agree well with the numerical simulation.
