Abstract

A true single-step process suitable for fabrication of micro-periodic structure in polymer films by two-photon initiated photopolymerization and laser ablation is presented. By the right choice of the irradiation energy, the irradiated zone is modified or ablated in the 1.44-micron-thick film. The mechanism of grating generation and the potential application of the gratings in integrated optics are discussed.
