Suppression of bend loss in writing of three-dimensional optical waveguides with femtosecond laser pulses
Zhengming Liu, Yang Liao, Zhiwei Fang +2
We provide a solution toward compact and low-loss three dimensional (3D) photonic circuits by femtosecond laser direct writing of 3D waveguides in fused silica. We suppress the ben…

Fabrication of polarization-independent single-mode waveguides in lithium niobate crystal with femtosecond laser pulses
Jia Qi, Peng Wang, Yang Liao +5
We report on fabrication of depressed cladding optical waveguides buried in lithium niobate crystal with shaped femtosecond laser pulses. Depressed cladding waveguides of variable…
