研究目的
Investigating the transmission properties and potential applications of compact MIM waveguide side-coupled with U-cavity in nanoscale integrated optical devices.
研究成果
The designed compact MIM plasmonic waveguide structures exhibit single and double PIT-like effects, with potential applications in nanoscale filters, refractive index sensors, and slow/fast light devices. The study demonstrates the tunability of transmission spectra through geometric parameter adjustments and highlights the structures' high sensitivity and FOM in refractive index sensing.
研究不足
The study is limited by the geometric parameters of the waveguide structures and the refractive index of the filling medium. Potential areas for optimization include the coupling distances and cavity lengths for enhanced PIT effects.
1：Experimental Design and Method Selection:
The study employs finite element method (FEM) and coupled mode theory (CMT) to analyze the transmission characteristics of the designed waveguide structures.
2：Sample Selection and Data Sources:
The samples are MIM plasmonic waveguides coupled with U-cavity and slot cavities, with parameters set to ensure only the fundamental mode can propagate.
3：List of Experimental Equipment and Materials:
The study uses numerical ports with boundary mode analysis and frequency domain solver with perfect matching layer (PML) absorbing boundary conditions.
4：Experimental Procedures and Operational Workflow:
The simulation involves setting geometric parameters, analyzing transmission spectra, and studying the effects of changing these parameters.
5：Data Analysis Methods:
The transmission characteristics are analyzed using FEM and CMT, with convergence analysis and non-uniform mesh grid for accuracy.
