Abstract

To study nano-scale optical local-field phenomena, an apertureless near-field scanning optical microscope (aNSOM) is an important tool. Herein, an aNSOM has been developed and is utilized for observing the local surface plasmon resonance, wave propagation, and nano-antenna enhancement of nanoprisms. The developed aNSOM, based on a commercial atomic force microscope, is integrated with homodyne and heterodyne interferometric techniques to detect the near-field amplitude and phase of nanostructures. With the help of mechanical system designs, different illumination direction s and detections for different applications can be achieved.
