Abstract

To promote the miniaturization and integration of devices, various optical components based on hybrid plasmonic waveguides have been proposed such as microring resonators and Y-splitter. However, their footprints are strongly limited by the radiation loss of the bends. Here, we propose and analyze a novel hybrid plasmonic waveguide (NHPW) which can be used to realize sharp bend with little radiation loss. Based on NHPW, ultracompact racetrack resonators are realized. A racetrack resonator with an outer radius of 0.5μm and straight waveguide of 0.1μm is constructed, which has an extinction ration of 12.56dB and a significantly large free space range of 265nm.
