  • 摘要:

    传统的解析理论设计方案存在计算复杂度高、有限解析解、耗时长等问题。为了解决以上问题,在传统的光器件设计基础上,提出一种依据逆向设计方法的分光比可调的光功率分束器方案。在1.92 μm×1.92 μm的紧凑区域内,引入Ge2Sb2Se4Te1(GSST)相变材料改变器件的折射率分布。利用直接二进制搜索算法搜索GSST晶态和非晶态的最优状态分布。设计实现同一种器件结构,分光比可调的T型光功率分束器。仿真分析了器件的初始结构、分光比、相变材料区域状态分布、制造容差以及光场分布。结果表明:分光比分别为1∶1、1.5∶1、2∶1的3种光功率分束器在波长1530 nm−1560 nm之间的最小相对误差分别为0.004%、0.14%和0.22%,在制造容差范围内传输曲线最大波动分别是0.95 dB、1.21 dB、1.18 dB。该分光器结构紧凑,在光通信和信息处理领域有着较大的应用潜力。
