Extended Data Fig. 3

Transition from the Si waveguide to a LiTaO3-on-insulator ridge waveguide. (a) Schematic of the tri-layer adiabatic transition. Mode profiles in the regions of interest are added. (b) Expected transmission from a Si waveguide to a ridge LiTaO3 waveguide as a function of the lateral misalignment. (inset) Mode in the LiTaO3-on-insulator waveguide.
