Micro-transfer printing of thin-film lithium niobate (TFLN), as a backend integration method, enables selective and localized placement of TFLN to silicon platform, facilitating the creation of complex, multi-material systems that combine lithium niobate with other components. In this study, we investigate the transfer printing technique for TFLN. We present experimental results from hybrid silicon-LN devices created using this method, including micro-transfer printed ring modulators, photonics crystal (PhC) modulators, and Bragg Grating modulators, among others.
