Description | In this article the far-field radiation analysis of near-field optical probes is presented. It is shown that the quality of probes used for near-field scanning microscopy imaging can be estimated using directional measurements of the far-field radiation patterns. Experimental results are compared with numerical modeling of far-field radiation performed using finite difference in time-domain method (FDTD) and with SEM characterization of real probe geometry. The effects of probe geometry on real measurement on different samples are studied as well. |
