Femtosecond laser micromachined optical waveguides in LiTaO3crystal

By using femtosecond laser micromachining, optical wave guides in both depressed cladding and dual-line configurations have been produced in LiTaO3 crystal. The guiding properties and the thermal stability have been investigated for both geometries, which exhibit different performance. Depressed cla...
