我们演示了使用倾斜的光纤光栅，以协助产生的红外表面等离子体上的金属薄膜涂层的平面的D形光纤。通过调节光的偏振态，强（>25 dB）共振的波长可在类似于1000 nm的范围内调谐，并且对光纤周围的任何水性介质的折射率高度敏感（灵敏度= 3365 nm）。(C)2008年美国光学学会。
We demonstrate the use of tilted fiber gratings to assist with the generation of infrared surface plasmons on a metal film coating the flat of a D-shaped fiber. The wavelength of the strong (>25 dB) resonance is tunable over similar to 1000 nm by adjusting the polarization state of the light and is highly sensitive to the refractive index of any aqueous medium surrounding the fiber (sensitivity= 3365 nm).
