Rapid prototyping of three-dimensional microfluidic mixers in glass by femtosecond laser direct writing.
The creation of complex three-dimensional (3D) microfluidic systems has attracted significant attention from both scientific and applied research communities. However, it is still a formidable challenge to build 3D microfluidic structures with arbitrary configurations using conventional planar lithographic fabrication methods. Here, we demonstrate rapid fabrication of high-aspect-ratio microflu...
متن کاملCompact 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 ...
متن کاملThree-dimensional direct femtosecond laser writing of second-order nonlinearities in glass.
We demonstrate that direct femtosecond laser writing in silver-containing zinc and gallium phosphate glass enables generation of three-dimensional (3D) optical second-order nonlinear microstructures having an χ(2) value about 2.5 times that of quartz. The proposed physical model involves photo-reduction, photo-dissociation, and migration of silver species within the glass matrix. 3D laser-writt...
متن کاملMechanisms of refractive index modification during femtosecond laser writing of waveguides in alkaline lead-oxide silicate glass
We report on the mechanisms responsible for the formation of optical waveguides upon femtosecond laser irradiation of an alkaline lead-oxide silicate glass. MicroRaman spectroscopy and nonlinear fluorescence were employed to probe the local glass network structure and the formation of optically active defects respectively. At low laser pulse energies, the laser modified region is formed by a si...
متن کاملDirect femtosecond laser writing of waveguides in As2S3 thin films.
Single-channel waveguides and Y couplers were fabricated in chalcogenide thin films by use of femtosecond laser pulses from a 25-MHz repetition rate Ti:sapphire laser. Refractive-index differentials (delta n > 10(-2)) were measured through interferometric microscopy and are higher than the typical values reported for oxide glasses. The dependence of the index differential on the peak intensity ...
