Abstract:

A study was performed on the optical nanowriting on azobenzene side-chain polymethacrylate thin films using near-field scanning optical microscopy (NSOM). The optical storage mechanism in azobenzene side-chain polymers is based on the isomerization cycles of the azobenzene side-chains between their cis and trans forms. The optical anisotropy was detected by coupling the red light at 690 nm with modulated polarization to the NSOM aperture.
