Abstract
In this work the mathematical modelling and detailed analysis of a dielectric based nanowire (NW) infused hybrid plasmonic waveguide (HPWG) with an aim to achieve high propagation length and increased effective area is reported in detail. Modal analysis is carried out to characterize modal parameters such as propagation length and energy confinement for various metal oxide metal (MOM) plasmonic waveguides combinations using commercial COMSOL Multiphysics 6.0. The research problem addressed in this work is propagation length of HPWG. Large propagation length is one of the major requirements in most of the SPR sensors and photonic circuits. In this direction, to enhance the propagation length this work presents a detailed modeling, optimization, and analysis of various MOM combinations are considered for optimizing the propagation length. Detailed analysis is carried out for various MOM combinations. The investigations shows that a propagation length of up to 2800 µm with high confinement is achieved for GaAs-SiO2-Ag combination. HPWG having high propagation length reported in this work finds potentials applications in many SPR sensors, Photonic integrated circuits and CMOS silicon (Si)-based photonics technology.
