摘要：The research on nanophotonic devices has made great progress during the past decades. It is the unremitting pursuit of researchers that realize various device functions to meet practical applications. However, most of the traditional methods rely on human experience and physical inspiration for structural design and parameter optimization, which usually require a lot of resources, and the performance of the designed device is limited. Intelligent algorithms, which are composed of rich optimized algorithms, show a vigorous development trend in the field of nanophotonic devices in recent years. The design of nanophotonic devices by intelligent algorithms can break the restrictions of traditional methods and predict novel configurations, which is universal and efficient for different materials, different structures, different modes, different wavelengths, etc. In this review, intelligent algorithms for designing nanophotonic devices are introduced from their concepts to their applications, including deep learning methods, the gradient-based inverse design method, swarm intelligence algorithms, individual inspired algorithms, and some other algorithms. The design principle based on intelligent algorithms and the design of typical new nanophotonic devices are reviewed. Intelligent algorithms can play an important role in designing complex functions and improving the performances of nanophotonic devices, which provide new avenues for the realization of photonic chips.

摘要：隐晶质玄武岩是白鹤滩水电站超大规模地下厂房洞室群中广泛揭露出的主要围岩类别之一,且普遍赋存隐微裂隙,开挖过程中展现出特殊的力学响应特征。综合采用CT扫描、高速摄像、声发射、扫描电镜等手段,分析了隐晶质玄武岩的变形破坏特征、裂纹扩展及声发射演化规律等,并探讨了其细观破坏机制。结果表明:完整试样应力-应变曲线光滑,加载至峰值强度时瞬间爆裂,声发射信号异常集中,碎裂破坏;含隐微裂隙试样应力-应变曲线呈锯齿状,出现多次表面剥落,整个过程声发射信号非常活跃,以劈裂破坏为主;含宏观裂隙试样应力-应变曲线呈双峰或多峰状,峰前原生裂隙局部滑移,第1次峰值时宏观破裂面形成,声发射信号集中于峰值应力跌落瞬间,以剪切破坏为主。隐晶质玄武岩细观破坏机制主要为矿物颗粒沿晶断裂和穿晶断裂。研究成果为准确认识并科学掌握白鹤滩地下厂房洞室群围岩的力学响应及其破裂演化特征奠定了坚实基础,也可为硬脆岩体高应力破坏的认识和灾害控制提供参考和借鉴。
