WitrynaWe propose a hybrid laser microfabrication approach for the manufacture of three-dimensional (3D) optofluidic spot-size converters in fused silica glass by a combination of femtosecond (fs) laser microfabrication and carbon dioxide laser irradiation. Spatially shaped fs laser-assisted chemical etching was first performed to form 3D hollow … WitrynaA method of manufacturing a semiconductor device includes modifying a first laser beam from a first laser to form a first linear-shaped laser beam and modifying a second laser beam from a second laser to form a second linear-shaped laser beam. The method further includes overlaying the first linear-shaped laser beam and the second linear …
