| Abstract(in English) | We propose a novel method to efficiently correct the aberration in a free-space optical switch, where a liquid-crystal-on-silicon (LCOS) is used to control the wavefront. A particle swarm optimization (PSO) method is applied to finding the optimum set of Zernike modes that compensates the aberration. We find out that the obtained coefficients of the lower-order modes and those of the higher-order ones exhibit a linear relationship when the optimization flow is interrupted by the local optima. We can drastically reduce the time for the calibration by using this relationship among the Zernike coefficients. This technique realizes low-loss optical switches without complex calibration procedure. |
