研究目的
Investigating the performance of a CMOS-compatible hybrid plasmonic slot waveguide (HPSW) with enhanced field confinement.
研究成果
The proposed HPSW structure provides significantly enhanced field confinement and a better tradeoff between field confinement and propagation length compared to traditional waveguides. It is fully compatible with semiconductor fabrication techniques, offering potential for high-performance nanoscale semiconductor-based plasmonics and photonics.
研究不足
The study is based on simulations, and practical fabrication challenges are not addressed. The tradeoff between modal attenuation and propagation distance still exists.
1：Experimental Design and Method Selection:
The study employs a finite element method (FEM) to simulate the modal properties of the HPSW.
2：Sample Selection and Data Sources:
The simulation uses a wavelength of 1550 nm with refractive indices for Si, SiO2, air, and Ag specified.
3：List of Experimental Equipment and Materials:
The commercial software COMSOL is used for simulations.
4：Experimental Procedures and Operational Workflow:
The study varies the thicknesses of different layers (Ag, Si, SiO2) to analyze their effects on field confinement and propagation length.
5：Data Analysis Methods:
The analysis includes calculating the confinement factor, propagation length, effective mode area, and figure of merit (FOM).
