Abstract

A tapered fiber plasmon sensor with a tip angle of about 30 degrees was fabricated to realize optical absorption and application to an optical sensor using localized plasmon in the 1500 nm wavelength band. The sharp tip angle of a single-mode fiber (SMF) was well controlled by using a highly GeO2-doped single-mode fiber (SMF) and optimizing the etching conditions with buffered fluoric acid. Gold nanoparticles (Au-NPs) with a diameter of 40 nm were deposited by treating the surface of a tipped SMF with silane coupling. The relationship between Au NPs deposition time and deposition ratio was studied to control Au NPs distribution and pursue higher sensitivities. The wavelength sensitivity of 662 nm/RIU was expected at Au NPs deposition ratio of 34.9 % in the analysis, and actually a high sensitivity of 677 nm/RIU at 35.3 % was experimentally demonstrated.

带有金纳米粒子的锥形光纤等离子体传感器在 1500 纳米波段的高灵敏度特性

为了实现光吸收并将其应用于利用 1500 nm 波段局部等离子体的光学传感器，我们制作了一种尖端角度约为 30 度的锥形光纤等离子体传感器。通过使用高度掺杂 GeO2 的单模光纤（SMF）并优化缓冲氟酸的蚀刻条件，单模光纤（SMF）的尖角得到了很好的控制。通过硅烷偶联剂处理有尖端的单模光纤表面，沉积了直径为 40 nm 的金纳米粒子（Au-NPs）。研究了金纳米粒子沉积时间与沉积比例之间的关系，以控制金纳米粒子的分布，追求更高的灵敏度。分析结果表明，金氧化物沉积比率为 34.9% 时，波长灵敏度预计为 662 nm/RIU，而实验结果表明，金氧化物沉积比率为 35.3% 时，灵敏度高达 677 nm/RIU。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
