All-optical modulation has been regarded as an effective method to solve the electrical bandwidth bottleneck problems existing in the current telecommunication network. By taking advantage of high photothermal conversion of two-dimensional (2D) MXene, a high-performance all-optical modulator is demonstrated. The polarization-dependent all-optical modulator exhibits a broadband intensity modulation behavior with a modulation depth of 15 dB. The response time of such all-optical modulator is approximately ten times than that of fiber-type MZI/MI-assisted all-optical modulator based on the thermal-optic effect. Besides, an all-optical information loading with a bit rate of 400 bit s −1 is successfully achieved. Therefore, it is anticipated that the all-optical modulator with the advanced optical structures and excellent 2D materials has extraordinary potentials for future optical information processing.

MXene-PVA薄膜用于高性能的高效全光调制器和全光信号处理

全光调制已被认为是解决当前电信网络中存在的电带宽瓶颈问题的有效方法。通过利用二维（2D）MXene的高光热转换，展示了一种高性能的全光调制器。偏振相关的全光调制器表现出宽带强度调制行为，调制深度为15 dB。基于热光效应，这种全光调制器的响应时间大约是光纤型MZI / MI辅助全光调制器的响应时间的十倍。此外，成功实现了以400 bit s -1的比特率进行全光信息加载。因此，
