Abstract

Strong transverse magneto-optical Kerr effect (TMOKE) on Au/Fe/Au surface plasmon (SP) gratings is demonstrated. Via the optimal design of this structure, the measured Kerr parameter is 0.03, which is 3 times larger than the maximal value ever reported on a plane magneto-optical SP substrate. Moreover, the Kerr parameter is very dispersive near the SP wavelength, which can be used for a high sensitive biosensor.
表面等离子体光栅强横向磁光克尔效应的观察
研究了Au/Fe/Au表面等离子体(SP)光栅的强横向磁光克尔效应(TMOKE)。通过对该结构的优化设计,测量到的Kerr参数为0.03,是平面磁光SP基板上所报道的最大值的3倍。此外,克尔参数在SP波长附近具有很好的色散性,可用于高灵敏度的生物传感器。
