Usually, the development of WGM microresonators for built-in lithium niobate photonics is accompanied by the improvement on the LNOI preparation technique. While in the early stage, z-Lower LN movies were typically chosen as a result of the constraints of lithographic tactics. can be consulted in Appendix B in [19].
