Abstract
Three-dimensional woodpile photonic crystal structures were recorded in films of polymeric photoresists polymethylcrylate (PMMA) and SU-8 films by femtosecond laser microfabrication technique. The fabricated structures consist of periodic arrays of extended elliptical void-channels in PMMA, and of solid elliptical rods of cross-linked polymer in SU-8. Their lattice periods of several micrometers and typical sub-micrometric feature sizes allowed to confirm presence of pronounced photonic stop-bands at infrared wavelengths around 2.0 - 8.0 μm.
