Abstract

Periodically poled lithium tantalate on insulator (PPLTOI) was successfully fabricated by applying a high-voltage electric field. The shape of the electrode, which determines the electric field distribution, as well as the poling time, and the strength of the electric field, are investigated in detail for the fabrication of periodically poled LTOI. By optimizing the poling parameters, the duty cycle of the inverted domain can be flexibly adjusted as well as be controlled to the optimal value of 50%. Moreover, the fabricated domain structure is uniform, and the standard deviation is less than 4.8%. The study presented in this work will pave the way for applications of LTOI in nonlinear integrated photonics.
