摘要:

科学界已经见证了对分层(即二维,2D)材料的研究的巨大扩展,最近越来越多地关注光子学的应用。层状材料对于在光子集成电路的受限几何结构中操纵光特别令人兴奋,其中关键材料特性包括强且可控的光-物质相互作用以及有限的光学损耗。层状材料具有可调的光学特性,相位是有前途的电光学,和一个多晶型物,建议一个丰富的设计空间的高度非微扰的光子集成器件的基础上相变功能。所有这些特征在带隙高于光子学相关的近红外(NIR)光谱带($\sim$ 0.5 - 1 eV)的材料中是明显的,这意味着它们可以在折射(即非吸收)应用中被利用。

英文摘要:

The scientific community has witnessed tremendous expansion of research on layered (i.e. two-dimensional, 2D) materials, with increasing recent focus on applications to photonics. Layered materials are particularly exciting for manipulating light in the confined geometry of photonic integrated circuits, where key material properties include strong and controllable light-matter interaction, and limited optical loss. Layered materials feature tunable optical properties, phases that are promising for electro-optics, and a panoply of polymorphs that suggest a rich design space for highly-nonperturbative photonic integrated devices based on phase-change functionality. All of these features are manifest in materials with band gap above the photonics-relevant near-infrared (NIR) spectral band ($\sim$ 0.5 - 1 eV), meaning that they can be harnessed in refractive (i.e. non-absorptive) applications.
