摘要
本文介绍了一种具有超低损耗的 D 型光子晶体光纤 (PCF) 传感器。该传感器能够检测折射率 (RI) 在 1.36 至 1.42 范围内的分析物。当被分析物的折射率为 1.36 时,传感器在 x 偏振方向的最大损耗仅为 23.25 dB/m。当被分析物的 RI 为 1.42 时,传感器在 x 偏振方向的最大波长灵敏度为 8000 nm/RIU,平均波长灵敏度为 4678 nm/RIU。传感器的设计是通过在 PCF 的侧面抛光表面镀上一层金膜来实现的。对于高灵敏度传感器来说,金的沉积可以在保持超低损耗的同时提供出色的光学性能。总体而言,所设计的基于侧面抛光平面金层的 D 型 PCF 传感器具有超低损耗、高灵敏度和稳定特性,在各种传感应用中具有巨大潜力。
Ultra-Low Loss D-Type Photonic Crystal Fiber Sensor Based on Surface Plasmon Resonance
A D-type photonic crystal fiber (PCF) sensor with ultra-low loss is presented in this paper. The sensor is capable of detecting analytes in the refractive index (RI) range of 1.36 to 1.42. When the RI of the analyte is 1.36, the maximum loss of the sensor in the x-polarized direction is only 23.25 dB/m. A maximum wavelength sensitivity of 8000 nm/RIU is obtained as the analyte has a RI of 1.42, and the sensor has an average wavelength sensitivity of 4678 nm/RIU in the x-polarization direction. The design of the sensor is implemented by coating the side-polished surface of the PCF with a gold film. For the high-sensitivity sensor, the deposition of gold can provide excellent optical performance while maintaining an ultra-low loss. In general, the designed D-type PCF sensor based on side-polished flat gold layer has great potential in various sensing applications due to its ultra-low loss, high sensitivity, and stable properties.
期刊介绍:
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
