Ultrafast optical properties and applications of anisotropic 2D materials

Nanophotonics, Volume 13, Issue 2, Page 107-154, January 2024.
Abstract Two‐dimensional (2D) layered materials exhibit strong light‐matter interactions, remarkable excitonic effects, and ultrafast optical response, making them promising for high‐speed on‐chip nanophotonics. Recently, significant attention has been directed towards anisotropic 2D materials (A2DMs) with low in‐plane crystal symmetry. These materials
