A hybrid optical fiber comprising metal electrodes, high performance polymers, and a highly nonlinear glass core is presented in this work as a novel, to the best of our knowledge, platform for mid-infrared nonlinear devices. The fiber allows for electrical tuning of the temperature by joule heating using a set of embedded tungsten wires. Unlike temperature tuning by an external heater, this results in a strong modulation, which introduces alternating signs of its dispersion. Enhanced spectral broadening through supercontinuum generation in the mid-infrared due to this modulation is investigated numerically.

基于硫族化物的混合光纤中的热可调色散调制

据我们所知，本文中提出了一种包含金属电极，高性能聚合物和高度非线性玻璃芯的混合光纤，这是一种新颖的中红外非线性设备平台。光纤允许通过使用一组嵌入的钨丝进行焦耳加热来对温度进行电调节。与通过外部加热器进行温度调节不同，这会导致强烈的调制，从而产生交替的色散信号。数值研究了由于这种调制而在中红外通过超连续谱产生增强的光谱展宽。
