Abstract

We demonstrate nanofabrication of photoreactive azobenzene molecular thin films using optical migration of molecules induced by local polarization in optical near-fields. Transportation and alignment control of the nanomaterial systems were investigated to modulate the excitation of the optical near-fields. Energy transfers from fluorescent molecules were observed along a planar boundary system of metals and dielectrics. The fundamental processes of tunneling energy that flowed to the metallic layer were evaluated from the angular distribution of scattered light in a far field, corresponding to the angular spectrum of scattered fields, including those of evanescent waves excited near the fluorescent molecules and nanostructures fabricated on azo molecular films.
