This review summarizes recent advances in the photonics of two-dimension transition metal carbides referred as MXenes. MXenes show outstanding nonlinear optical absorption and can serve as excellent mode-lockers to produce ultrafast pulse lasers at the broad range from visible to mid-infrared regions. Particularly, metallic MXenes have great advantages for long-wavelength applications and 3000-nm mode-locked free-space lasers are readily fabricated using MXene-deposited saturable absorber mirrors. MXenes also have significant terahertz electromagnetic shielding efficiency. All-optical modulators using the nonlinear optical properties of MXene are realized at the visible and/or terahertz range. Metamaterials composed of periodically arranged MXene disks can act as broadband perfect absorbers along with surface plasmon enhancement. We believe that these emerging MXene 2D materials will play an important role in variety of future photonic technologies including nonlinear optics, el...

二维过渡金属碳化物（MXenes）的宽带超快光子学

这篇综述总结了二维过渡金属碳化物（称为MXenes）的光子学的最新进展。MXenes具有出色的非线性光学吸收能力，可以用作出色的锁模器，以生产从可见光到中红外范围广泛的超快脉冲激光。特别地，金属MXene对于长波长应用具有巨大优势，并且使用MXene沉积的可饱和吸收镜可轻松制造3000 nm锁模自由空间激光器。MXenes还具有显着的太赫兹电磁屏蔽效率。利用MXene的非线性光学特性的全光调制器在可见光和/或太赫兹范围内实现。由周期性排列的MXene圆盘组成的超材料可以充当宽带完美吸收体，并增强表面等离激元。
