3D Chiral Plasmonic Metamaterials Fabricated by Direct Laser Writing: The Twisted Omega Particle

Three-dimensional bichiral plasmonic crystals fabricated by direct laser writing and electroless silver plating.

3D-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, ...

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 ...

Compact 3D Microfluidic Channel Structures Embedded in Glass Fabricated by Femtosecond Laser Direct Writing

We demonstrate rapid fabrication of complex three-dimensional (3D) microfluidic channels with lengths up to ~6.0 cm within a tiny volume down to ~80 nl in glass substrates by femtosecond laser direct writing, which, to the best of our knowledge, is the longest microfluidic channel directly embedded in glass by femtosecond laser microprocessing. The fabrication mainly includes the following two ...

Bulk 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...
