We demonstrate ultra-high Q factor microring resonators close to theintrinsic material absorption limit on lithium niobate on insulator. Themicrorings are fabricated on pristine lithium niobate (LN) thin film waferthinned from LN bulk via chemo-mechanical etching without ion slicing and ionetching. A record-high Q factor up to times ten to the power of 8th at thewavelength of 1550 nm is achieved because of the ultra-smooth interface of themicrorings and the absence of ion induced lattice damage, indicating anultra-low waveguide propagation loss of about 0.28 dB per meter. The ultra-highQ microrings will pave the way for integrated quantum light source, frequencycomb generation, and nonlinear optical processes.
