研究目的
Investigating the design and simulation of a compact band-pass filter using stub loaded plasmonic MIM waveguide for applications in plasmonic integrated circuits.
研究成果
A new stub loaded plasmonic MIMSIR waveguide based dual band pass-band filter has been implemented, demonstrating two passbands at 1358nm and 1631nm with low insertion loss. The compact design suggests potential applications in high-density multi-band PICs.
研究不足
The study is limited to numerical simulations using CST Microwave Studio suite, without experimental validation. The applicability of the proposed filter in real-world photonic integrated circuits needs further investigation.
1：Experimental Design and Method Selection:
The study involves the design and numerical analysis of a plasmonic band-pass filter based on two-stubs, with pass-band realization through adjustment of resonator lengths and width. The CST Microwave Studio suite is used for simulation.
2：Sample Selection and Data Sources:
The study focuses on a nanoplasmonic MIM waveguide with specific dimensions (W1=80 nm, W2=320 nm, lengths L1=1700 nm, L2=150 nm, L3=400 nm).
3：List of Experimental Equipment and Materials:
CST Microwave Studio suite for simulation.
4：Experimental Procedures and Operational Workflow:
The transmission spectrum of the BPF is studied with adjustments to the lengths and width of the waveguide, keeping the effective index of the insulator fixed.
5：Data Analysis Methods:
The transmission and reflection coefficients are analyzed at THz frequencies, with field distributions examined at specific wavelengths.
