Microstructure in lithium niobate by use of focused femtosecond laser pulses

Abstract

Using a tightly focused femtosecond laser of microjoule energy per pulse, we produced optical waveguide inside the pure Lithium Niobate (LN) substrate. This technique has the potential to generate not only channel waveguide but three-dimensional photonic devices. In this letter, a Y splitter has been fabricated in LN. The output optical fields through the… (More)
