采用湿法化学刻蚀和机械裂解技术制备了附着在锥形光纤上的金纳米针尖。在尖端激发局域表面等离子体共振(通过改变尖端尺寸可在500到850 nm之间调谐)，并通过光纤将信号传输到光学分析仪，使该设备成为等离子体增强的近场探测器。一个简单的腔模型被用来解释在数值模拟中观察到的共振。
A wet-chemical etching and mechanical cleaving technique is used to fabricate gold nanotips attached to tapered optical fibers. Localized surface plasmon resonances (tunable from 500 to 850 nm by varying the tip dimensions) are excited at the tip, and the signal is transmitted via the fiber to an optical analyzer, making the device a plasmon-enhanced near-field probe. A simple cavity model is used to explain the resonances observed in numerical simulations.
