Optical waveguide array-optical fiber array automatic butt-coupling parallel index optimization method

Abstract

The invention provides an optical waveguide array-optical fiber array automatic butt-coupling parallel index optimization method. The optical waveguide array-optical fiber array automatic butt-coupling parallel index optimization method comprises that mapping between an optical waveguide array-optical fiber array auto-aligning physical parameter and a parallel index optimization model is established, and a first objective function and a second objective function are obtained; a maximum evolutional generation is set, input single-mode fiber arrays and output single-mode fiber arrays enter specified spatial positions in a specified direction and attitude according to the regulation of each individual, optical power values of two or more than two waveguide channels are read, recorded and stored, and the Pareto sequence and the crowding distance are calculated; evaluation of each individual in one generation cluster is completed, a next generation cluster is generated by means of intersection, variation and lowliest place elimination, the evolutional generation is accumulated, whether the evolutional generation reaches the maximum evolutional generation or not is determined, if the evolutional generation reaches the maximum evolutional generation, the process is finished; if the evolutional generation does not reach the maximum evolutional generation, the intersection step is returned. According to the invention, the low-loss rapid butt-coupling automation degree and the working efficiency of an optical fiber array-waveguide device-optical fiber array system are effectively improved.
