Analysis of optical nano-antennas

Near-field infrared microscopy, enabled by neaSCOPE systems, can be used to analyze the local field of photonic structures.

Detailed analysis of nano-antennas

Near-field images of the resonant infrared antenna show signs of dipolar oscillation mode on the golden rod, which was verified by classical infrared spectroscopy (far field). The amplitude image has a high signal at the ends of the rods, which are phase shifted by 180 °. If the antenna structure is modified (e.g. by a cut in the center of the golden rod), near-field images reveal two dipolar oscillation modes on the segments. Systematic studies make it possible to analyze the coupling between segments and to characterize the optical properties of antenna structures. In addition, polarized measurements make it possible to filter out specific components of the optical field associated with photonic structures or devices and to examine fields, e.g. in the antenna gap.
