Advances in Responsive Photonic Crystal Sensors

光子晶体是一种具有周期性折射率变化的新型光学材料,是由不同折射率的介质周期性排列而成的微观结构,其所具有的周期性结构会影响光在内部的传播,因此能够实现对光的精准调控。将具有光子晶体结构的材料和具有响应性的材料相结合,能够制备出响应性光子晶体材料,其不仅具有光子晶体材料本身对光波的调控能力,如通过周期性结构产生光子带隙来禁止或允许特定频率的光波传播,而且能够对外界刺激产生响应,进而改变自身光学性质。因其具有独特的响应性光学特性,在显示技术、传感器、智能材料、防伪标签等领域展现出了广泛的应用前景。本文主要介绍了刺激响应性光子晶体传感器的研究进展,并总结了不同类型响应性光子晶体传感器的制备方式及应用。

Photonic crystal is a new type of optical material with periodic refractive index change.It is a microstructure formed by periodic arrangement of media with different refractive index.Its periodic structure will affect the propagation of light in the interior,so it can achieve accurate control of light.By combining a material with a photonic crystal structure and a responsive material,a responsive photonic crystal material can be prepared,which not only has the ability of the photonic crystal material itself to regulate light waves,such as the photonic band gap generated by the periodic structure to prohibit or allow the propagation of specific frequencies of light waves,but also can respond to external stimuli,thus changing its own optical properties.Because of its unique responsive optical properties,it has shown a wide range of application prospects in display technology,sensors,smart materials,anti-counterfeiting labels and other fields.This paper mainly introduces the research progress of stimulation-responsive photonic crystal materials,and summarizes the preparation methods and applications of different types of responsive photonic crystal materials.
