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.
