在这篇论文中，我们展示了一种基于碳纳米管(CNT)/聚合物复合材料的光纤锥的非线性光学器件。利用该器件实现了基于四波混频的10 Gb/S不归零信号的波长转换。此外，我们还研究了波长调谐和双光子吸收，并估算了埋入锥形光纤中的碳纳米管的有效非线性系数为1816.8 W(-1)Km(-1)。
In this paper, we demonstrate a nonlinear optical device based on a fiber taper coated with a carbon nanotube (CNT)/polymer composite. Using this device, four wave mixing (FWM) based wavelength conversion of 10 Gb/s Non-return-to-zero signal is achieved. In addition, we investigate wavelength tuning, two photon absorption and estimate the effective nonlinear coefficient of the CNTs embedded in the tapered fiber to be 1816.8 W(-1)km(-1).
