| Popis: | A superperiodic metal nanoslits device is a surface plasmon resonance optical diffraction grating in which each line of the grating consists of an array of finite number metal nanoslits. The metal nanoslits, upon optical excitations, support localized surface plasmon resonance. The superperiod of the nanoslits causes the coherent radiation of the surface plasmon resonance into the far field with angular dispersion. Therefore, localized surface plasmon resonance in the metal nanoslits can be measured with a CCD or a linear photodetector array. In this Letter, we describe a surface plasmon resonance spectral sensor using a superperiodic gold nanoslits array without using an external optical spectrometer. |
