中文说明：利用模拟退火算法实现光学模式转换，可以使转换的速率大幅度提高。模拟退火算法是一种全局优化算法，可以使得到的解跳出局部最优解从而得到全局最优解。利用相位掩模版得到的模式转换效率比较低，将此算法用到模式转换中来，可以使转换效率大幅度提高。
English Description：
Using simulated annealing algorithm to realize optical mode conversion can greatly improve the conversion rate. Simulated annealing algorithm is a global optimization algorithm, which can make the solution jump out of the local optimal solution and get the global optimal solution. The efficiency of mode conversion by using phase mask is low, and the efficiency can be greatly improved by using this algorithm in mode conversion.
