Mode defletion in lithium niobate waveguide via elecctro-optic effect and its application for beam smoothing

In this paper, we establish a straight waveguide model which is made of electro-optic material: lithium niobate. The refractive index profile of the waveguide can be slightly electro-optically manipulated, so that the optical mode can be deflected and reshaped in the transmitted direction of waveguide. When the mode deflection can be modulated via the high speed electro-optic effect, the temporally and spatially beam smoothing can be potentially achieved for the application of inertial confinement fusion system.
