Abstract-In this paper, we investigate numerically the light transverse localization in double ring waveguide array with correlated off-diagonal disorder. To this end, the tight-binding equation has been solved numerically (with MATLAB) for different values of correlation exponents. Numerical results show that when the correlation exponent is below some characteristic value, participation rate is small and transverse localization is occurred. In contrast, long-range correlation with high values of correlation exponent impedes localization and increases the transverse spreading of the wavepacket.
