摘　　要：针对光子集成技术中,理论优化光功率分配器结构的方法存在复杂度高、耗时长、尺寸大等不足。利用逆向设计思维,提出一种E-DBS算法,研究并优化出了结构紧凑,大小仅为2.16μm×2.16μm,能实现多种分光比、高效率输出的集成光功率分配器。通过仿真设计,验证了1∶1、1∶1.2、1∶1.5、1∶2四种不同分光比的集成光功率分配器。在波长为1 400~1 600 nm, 4种光功率分配器在仿真条件下,分光比的误差绝对值均控制在0.605 dB之内,仿真实验结果符合预期目标。In the photonic integration technology,the method of optimizing the structure of optical power divider based on theory had some disadvantages,such as high complexity,long time-consuming and large size.An E-DBS algorithm was proposed by using inverse design thinking,and an integrated optical power divider with compact structure and size of 2.16μm×2.16μm is optimized,which can achieve multiple splitting ratio and high efficiency output.Through simulation design,the integrated optical power splitter with four different splitting ratios of 1∶1,1∶1.2,1∶1.5 and 1∶2 is verified.The device size is compact,only 2.16μm×2.16μm.Within the wavelength range from 1400 nm to 1600 nm,under the simulation conditions,the absolute error of the four optical power splitter designed is controlled within 0.605 dB,and the simulation result is in line with the expected target.
