Wavelength-scale light concentrator made by direct 3D laser writing of polymer metamaterials
We report on the realization of functional infrared light concentrators based on a thick layer of air-polymer metamaterial with controlled pore size gradients. The design features an optimum gradient index profile leading to light focusing in the Fresnel zone of the structures for two selected operating wavelength domains near 5.6 and 10.4 μm. The metamaterial which consists in a thick polymer ...
متن کاملBulk Negative Index Photonic Metamaterials for Direct Laser Writing
We show the designs of oneand two-dimensional photonic negative index metamaterials around telecom wavelengths. Designed bulk structures are inherently connected, which render their fabrication feasible by direct laser writing and chemical vapor deposition. ©2008 Optical Society of America OCIS Codes: (350.3618) Left-handed materials; (260.2065) Effective medium theory Report Documentation Page...
متن کاملDirect laser writing of 3D architectures of aligned carbon nanotubes.
Direct laser writing through two-photon polymerization lithography is used to fabricate 3D nanostructures containing aligned single-wall carbon nanotubes (SWCNTs). SWCNTs are aligned in the laser scanning directions while they are embedded in the structure. The alignment is induced by spatial confinement, volume shrinkage, and the optical gradient force. This method is expected to lead to new a...
متن کاملNumerical analysis of the sub-wavelength fabrication of MTMO grayscale photomasks by direct laser writing.
Metal-transparent-metallic-oxide (MTMO) grayscale photomasks fabricated by direct laser writing have been proposed in recent years. The fabrication mechanism is attributed to light-induced melt-oxidization. The temporal-spatial distribution of temperature fields of indium film-glass samples under a laser pulse have been calculated by the Finite-Difference Time-Domain method. The laser action ar...
متن کامل3D-2D-3D photonic crystal heterostructures fabricated by direct laser writing.
Using direct laser writing, we fabricate photoresist templates for 3D-2D-3D photonic crystal heterostructures for what we believe to be the first time. The optical properties of these structures are directly compared with the theoretical ideal, revealing good agreement and hence good sample quality. This provides an experimental starting point for the microfabrication and testing of broadband, ...
