▎ 摘　　要

This paper presents systematic design and analysis of a compact ultra-low loss graphene-based multilayer hybrid plasmonic waveguide (GMLHPW). The simulation results indicate that the propagation length of the surface plasmon polaritons (LSPP) is equal to 45.28 mm at the wavelength of 1550 nm for moderate value of the graphene's chemical potential and a small carrier mobility. To our knowledge, the obtained LSPP is the highest value among the hybrid plasmonic waveguides proposed to date. However, more enhancement of LSPP is realizable by increasing the graphene's chemical potential and carrier mobility. Also, the effective mode area and the dimensions of the GMLHPW core are 0.0547 mu m2 and 180 x 640 nm2, respectively; indicating the potential of the designed waveguide to realize compact optical integrated circuits. An add-drop microring resonator has been designed based on the GMLHPW with a higher Q factor than that of the recent work. This device is a good candidate in the signal processing applications.
