We propose an alternative technique for generating a tunable supercontinuum in a liquid-filled chalcogenide capillary optical fiber exhibiting three zero-dispersion wavelengths. To investigate the tunable supercontinuum, a nonlinear Schrödinger equation is solved to understand the soliton pulse dynamics. Utilizing temperature-assisted dispersion tailoring, the generation of dispersive waves that are tunable within a broad wavelength range of 3630–4650 nm and 2230–2560 nm is reported, with detailed investigations of various spectrograms confirming the predictions of dispersive waves through phase-matching characteristics. Also, temperature-controlled soliton spectral tunneling is numerically predicted in the same fiber and depends on the spectral width of the normal dispersion region between two anomalous regions.

硫族化物玻璃基毛细管光纤中温度辅助的宽可调超连续谱的产生

我们提出了一种替代技术，该技术可在显示三个零色散波长的液体填充硫族化物毛细管光纤中生成可调超连续谱。为了研究可调超连续谱，求解了非线性Schrödinger方程，以了解孤子脉冲动力学。据报道，利用温度辅助色散调整技术，可以在3630–4650 nm和2230–2560 nm的宽波长范围内调节色散波的产生，并通过对各种频谱图的详细研究证实了通过相匹配特性预测色散波。同样，在同一根光纤中对温度控制的孤子光谱隧穿进行数值预测，并且取决于两个异常区域之间的正常色散区域的光谱宽度。
