Abstract
In order to improve anti-jitter capability of a fiber coupling structure, a fiber array with self-focusing lens was designed, the optical fiber array was controlled by means of annealing algorithm and the optimal visual axis alignment position was found. The fiber array and simulated annealing algorithm were analyzed theoretically, and the data of coupling efficiency was achieved. Experimental results show that the simulated annealing algorithm can find the optimal visual axis alignment position. When spot center moving less than 2.5mm on the coupling surface, the power coupled in the fiber fluctuates less than 35%. It can meet the requirements of free space optical communication system.
