本学期第一次午餐会邀请我院罗杰老师做学术报告。
报告题目：光子掺杂与光子反掺杂
报告人: 罗杰老师
报告时间：3月18日（周一）中午12：00
报告地点：博习楼221会议室
报告摘要：Impurities usually play an important role in modifying the bulk properties of electronic or electromagnetic materials. Very recently, a “doping” effect of impurities in epsilon-near-zero media has been proposed. In this talk, I will first demonstrate how to use the doping discipline to control the absorption of light so as to realize geometry-invariant coherent perfect absorption (CPA). Such a CPA has been experimentally verified in microwaves. Secondly, I will demonstrate a way to break the doping discipline and realize the extraordinary property of impurity-immunity (photonic “anti-doping” effect) by using parity-time symmetry. In this case, the system exhibits the rare property of perfect transmission irrespective of embedded impurities of almost any materials and shapes.
