Local Refractive Index Change by Tip-Enhanced Femtosecond Laser for Surface Photonic Crystal Creation

Denis E. Tranca, Radu Hristu, Stefan G. Stanciu, and George A. Stanciu

Your library or personal account may give you access

Abstract

The local refractive index of polymethyl methacrylate is modified due to low power femtosecond laser exposure in the proximity of a sharp metallic tip. Such modified nanoscale-sized regions can be used for photonic crystals creation.
