We report on the femtosecond laser fabrication of micro-channels of sub-micrometer cross section recorded in polymethylmethacrylate (PMMA) films in a single processing step. Both axial lengths of an elliptical cross section smaller than 0.4 μm were achieved for a fabrication irradiance close to the dielectric breakdown of PMMA. Femtosecond pulsed irradiation was scanned along the three-dimensional...
Fine-tuning of stop band positioning, ranging from several nano meters to several tens of nano meters, was achieved through sequential thin layer coating of semiconductor materials onto the constituent particles of a three dimensional silica-based photonic crystal. Several semiconductor materials, including TiO2, CdS, and ZnSe, were successfully used to achieve a controllable red-shift of the stop...
