Fabrication and Chemical Modifications of Photonic Crystals Produced by Multiphoton Lithography

Abstract

Nanoscale features as small as 65 ± 5 nm have been formed reproducibly by using 520<lb>nm femtosecond pulsed excitation of a 4,4'-bis(di-n-butylamino)biphenyl chromophore to<lb>initiate crosslinking in a triacrylate blend. Dosimetry studies of the photoinduced<lb>polymerization were performed on chromophores with sizable two-photon absorption<lb>cross… (More)
