Abstract
A lithium niobate on insulator (LNOI) optical waveguide including a first region, a second region, and a third region, a substrate layer extending across the first region, the second region, and the third region, and a first cladding layer disposed on the substrate layer across the first region, the second region, and the third region. The LNOI optical waveguide further includes a lithium niobate (LN) layer disposed on the first cladding layer across the first region and the second region. The LN layer has a planar surface in the first region and a vertically tapered surface in the second region, and a dielectric strip in contact with the LN layer across the first region and the second region, and in contact with the first cladding layer across the third region.
