研究目的
To develop a tunable photonic crystal fiber (PCF) polarized filter with a gold coating and liquid filling for simultaneous polarization filtering at communication wavelengths of 1310 nm and 1550 nm.
研究成果
The developed tunable PCF polarization filter based on hybrid SPR can allow separate adjustments for different wavebands. The resonance strength in the y-direction was larger than that in the x-direction. The confinement loss of the y-polarized mode could reach 251.5 dB/cm at a wavelength of 1.31 μm and 375.3 dB/cm at a wavelength of 1.55 μm. Due to its compact structure, the proposed PCF will have important applications in integrated optical communication.
研究不足
The study acknowledges that the optical fiber structure could be optimized further to obtain better results.
1：Experimental Design and Method Selection:
The study used the full-vector finite-element method (FV-FEM) to analyze the PCF filter. The material dispersion in pure silica was calculated using the Sellmeier equation, and the permittivity of the gold was calculated using the Drude–Lorentz model.
2：Sample Selection and Data Sources:
The PCF was designed with a rectangular lattice structure, with specific diameters for air holes and gold coating.
3：List of Experimental Equipment and Materials:
The PCF was fabricated using ultrasonic drilling, and the liquid selective filling was applied using the two-photon direct laser writing technique. Metal-coated and metal-filled PCF was obtained using vacuum metal spatter and high-pressure microfluidic chemical deposition.
4：Experimental Procedures and Operational Workflow:
The study involved calculating the effects of different structural parameters on the confinement loss and dispersion characteristics.
5：Data Analysis Methods:
The mode loss was calculated using the imaginary part of the effective index.
