前景:声子极化激元用于红外光电子学

Perspective: Phonon polaritons for infrared optoelectronics

Christopher R. Gubbin, Simone De Liberato, Thomas G. Folland

摘要:

近年来,由于声子极化激元能够将光压缩到极小的尺寸,低损耗,并且能够支持各向异性传播,因此对声子极化激元进行了重要的基础研究。从这个角度来看,在简要回顾了中红外光电子学的现状后,我们将评估基于声子极化激元的纳米光子学用于红外(3-100 $\mathrmμ$ m)光源、检测器和调制器的潜力。这些将在Reststrahlen区域中工作,在该区域中传统的半导体光源变得无效。根据过去几年的结果,我们将勾勒出一些有希望的路径来创建这样的设备,我们将评估其实际的优点和缺点相比,其他方法的红外光电子学。

英文摘要:

In recent years there has been significant fundamental research into phonon polaritons, owing to their ability to compress light to extremely small dimensions, low-losses, and ability to support anisotropic propagation. In this perspective, after briefly reviewing the present state of mid-infrared optoelectronics, we will assess the potential of phonon-polariton based nanophotonics for infrared (3-100$\mathrmμ$m) light sources, detectors and modulators. These will operate in the Reststrahlen region where conventional semiconductor light sources become ineffective. Drawing on the results from the past few years, we will sketch some promising paths to create such devices and we will evaluate their practical advantages and disadvantages when compared to other approaches to infrared optoelectronics.
