基于相变材料的可调纳米光学

Tunable Nanophotonics by Phase Transition Materials


报告摘要 (Abstract):
       
近年来,混合光电系统得到了广泛研究用以在系统层面提高探测、光通信和数据处理的性能。由于能够被集成在智能系统里,拥有更小更快更节能特性的可调纳米光学器引起来大量的注意。本讲座将介绍基于相变材料的新器件,重点介绍基于二氧化钒的可编程超材料和一个动态可调的微光机电系统。最后,本讲座将讨论一种特殊的纳米光学材料,梯度介电常数材料。
Currently, dynamic functionalities in hybrid electronic–photonic systems are being widely pursued to further improve the system——level performance in sensing, optical communication and data processing. Tunable nanophotonic devices, featuring a smaller size, faster
performance, and better energy efficiency, have drawn tremendous attention in recent years due to their potential integration with smart technology. In this talk, new device designs utilizing phase transition materials will be introduced. This talk will focus primarily on a vanadium dioxide based reprogrammable metacanvas and a micro-electro-opto-mechanical system (MEOMS), which is dynamically tunable by multiple stimuli. In addition, a unique nanophotonic system, gradient permittivity materials, will be discussed.
