Optical waveguide array are attractive for high-speed, wide-angle optical beam steering or deflection, but optical waveguide arrays radiate undesirable sidelobes. It is shown that suppression of sidelobes can be accomplished by configuring array elements in nonuniform pattern. Tow kinds of arrangement of linear changed spaced optical waveguide array are discussed. Sidelobes can be suppressed deeply. Especially, the light path area ratio can be improved to 71.9% by using symmetrical structure array. Steering characteristic shown that the maximum steering degree of 240(-3dB) can be obtained by nonuniform spaced optical waveguide array.
