All‐optical devices based on 2D materials have attracted great attention for desirable applications, such as communications and signal processing. However, the previously reported all‐fiber all‐optical devices utilizing the interferometer structures greatly limit their practical applications due to the poor anti‐interference ability and slow modulation rate. In this work, an all‐optical device has been demonstrated based on a microfiber knot resonator (MKR) deposited with Ti₂CT_x MXene, exhibiting a large photothermal conversion efficiency and high thermal conductivity. Experimental results show that the proposed all‐optical device is capable of producing a high‐performance phase and intensity modulation with a high modulation efficiency, fast response time, and good stability. Therefore, it is anticipated that the MKR‐based all‐optical devices based on 2D materials can pave the way to a new design of high‐performance all‐optical devices and have great potentials in the future optical information processing.

基于二维Ti2CTx MXene的超细纤维结谐振器全光控制

基于2D材料的全光学设备在诸如通讯和信号处理等理想应用中引起了极大的关注。但是，先前报道的利用干涉仪结构的全光纤全光器件由于其抗干扰能力差和调制速率慢而极大地限制了它们的实际应用。在这项工作中，已经证明了基于沉积有Ti ₂ CT _x的超细纤维结谐振器（MKR）的全光器件MXene，具有高的光热转换效率和高的热导率。实验结果表明，提出的全光器件能够产生高性能的相位和强度调制，调制效率高，响应时间快，稳定性好。因此，可以预见的是，基于二维材料的基于MKR的全光学设备可以为高性能全光学设备的新设计铺平道路，并在未来的光学信息处理中具有巨大的潜力。
