Paper Abstract
An apertureless near-field scanning optical microscope (a-NSOM) setup is described. Special
consideration is given to important system components. Surface plasmons are defined, as is their relationship to a-
NSOM and their interaction with the scanning probe tip. We used this set-up to measure a metal-dielectric-metal
(MDM) antenna integrated with a quantum cascade laser (QCL). The former is introduced and described. The role
of the atomic force microscope (AFM) in the experiment is laid out and explained. Finally, the lock-in amplifier is
explained. Next, the system setup is introduced and explained from the point of view of the light path taken by
light generated in the laser. Finally, results are given for the MDM single nanorod antenna and the coupled MDM
nanorod antenna. Simulation, topography, and NSOM images are shown. Lastly, several experimental issues are
discussed as well as other types of NSOM.
