Dammann gratings as integratable micro-optical elements created by laser micronanofabrication via two-photon photopolymerization

Abstract

Dammann gratings, as beam splitters and coherent signal generators, were produced in a short fabricating cycle by femtosecond laser fabrication via two-photon photopolymerization. These holograms that each generated $2\times 2$, $3\times 3$, $4\times 4$, $5\times 5$, and $6\times 6$ spot sources in the fan-out demonstrated diffraction efficiency of 36%, 25%, 29%, 52%, and 49%, respectively, comparable with the theoretical values. This work shows the promising prospect of femtosecond laser fabrication in compatibly manufacturing various micro-optical devices including Dammann gratings and their integrated systems.
