Abstract :
Optical modulation of one-dimensional waveguide array obtained in lithium niobate using femtosecond laser radiation is studied to modify the discrete diffraction characteristics of light beam within this waveguide system. It has been shown that such a modulation is available at relatively low optical power due to the photorefractive nonlinearity of this crystal.
