摘要
介绍了10.6 μm波段扫描负折射功率的实时探测系统, 在实验上为探测光子晶体光频波段负折射现象提供了实验平台。该系统通过数据采集卡实现计算机对旋转台及平移台的控制,在以光子晶体样品为探测中心的轨道上,对折射光的整个空间功率分布进行实时采集和绘图。这一实验系统能够精确便捷地实现负折射现象在光频波段的探测。根据折射光最大光功率出现的位置,测得光束通过光子晶体样品的负折射现象, 而且与理论结果基本吻合。
Abstract
A real-time detection system in 10.6 μm wavelength is introduced which is applied to experimental verification of negative refractive phenomena in photonic crystal at optical frequencies.
