摘要：
The structure of a strip LiNbO3 waveguide clad with a planar LiNbO3 waveguide is proposed to fabricate a long- period waveguide grating ( LPWG). It is shown theoretically that an LPWG device based on such a special LiNbO3 waveguide structure is of the merit of thermal stability. The methods for fabrication of planar waveguide, channel waveguide and grating are suggested and discussed. Detailed design consideration is exempli. ed based on a soft- proton- exchange planar waveguide clad Ti- di. used LiNbO3 ( Z- cut) strip waveguide.
