Liquid-core fibers offer local external control over pulse dispersion due to their strong thermodynamic response, offering a new degree of freedom in accurate soliton steering for reconfigurable nonlinear light generation. Here, we show how to accurately control soliton dynamics and supercontinuum generation in carbon disulfide/silica fibers by temperature and pressure tuning, monitored via the spectral location and the onset energy of non-solitonic radiation. Simulations and phase-matching calculations based on an extended thermodynamic dispersion model of carbon disulfide confirm the experimental results, which allows us to demonstrate the potential of temperature detuning of liquid-core fibers for octave spanning recompressible supercontinuum generation in the near-infrared.

液芯光纤中孤子动力学的热力学控制

液芯光纤由于其强大的热力学响应而提供了对脉冲色散的局部外部控制，为精确的孤子转向提供了新的自由度，从而可重新配置非线性光。在这里，我们展示了如何通过温度和压力调节来精确控制二硫化碳/二氧化硅纤维中的孤子动力学和超连续谱的产生，并通过光谱位置和非孤子辐射的起始能量进行监测。基于扩展的二硫化碳热力学色散模型的仿真和相位匹配计算证实了实验结果，这使我们能够证明液芯光纤温度失谐的可能性，从而在近红外范围内产生倍频程的可压缩超连续谱。
