摘要
全光调制器在全光信号处理和通信等全光应用中起着重要的作用。主要研究了基于MoS2-PVA薄膜实现的全光调制器。此外, 也验证了WSe2-PVA薄膜也可实现全光调制。该器件利用热光效应, 结合偏振干涉实现了全光调制, 得到了长时间稳定输出的调制信号。将980 nm的脉冲信号作为控制光, MoS2或WSe2吸收光产生热量, 使薄膜的折射率发生改变, 从而改变1 550 nm信号光的偏振态, 实现980 nm控制光对1 550 nm光的调制。得到的MoS2-PVA薄膜全光调制器的上升沿时间为526 μs。
Abstract
All-optical modulator plays an important role for various all-optical applications in optical communication. An all-optical modulator was mainly investigated based on few-layer molybdenum disulfide (MoS2)-polyvinyl alcohol (PVA) thin films. In addition, an all-optical modulator based on few-layer tungsten disulfide (WSe2)-polyvinyl alcohol (PVA) thin film was also demonstrated. The modulator was based on polarization interference and the thermo-optic effect of TMDs-PVA thin film. A long-time stable modulated output was obtained. By absorbing the pump at 980 nm, MoS2 or WSe2 generates heat, changes the refractive index of thin film and modifies the polarization of the incident light at 1 550 nm. The obtained thermal all-optical modulator based on MoS2-PVA thin film has a rise time of 526 μs.
