We numerically demonstrate that noise properties of picosecond mid-infrared (mid-IR) supercontinuum (SC) in the anomalous region of a chalcogenide photonic crystal fiber (PCF) can be effectively controlled by a weak continuous wave (CW) trigger. Detailed simulation results show that in the mid-IR region, the characteristics of SC, including spectral bandwidth, temporal coherence, and signal-to-noise ratio (SNR), can be greatly enhanced by the CW trigger at selected wavelengths. The present study provides valuable insight into the CW-triggered mid-IR SC under the influence of modulation instability (MI) and stimulated Raman scattering (SRS).

弱连续波触发硫系光子晶体光纤中红外超连续谱产生

我们从数值上证明了硫属化物光子晶体光纤 (PCF) 异常区域中皮秒中红外 (mid-IR) 超连续谱 (SC) 的噪声特性可以通过弱连续波 (CW) 触发器进行有效控制。详细的仿真结果表明，在中红外区域，CW 触发在选定波长下可以大大增强 SC 的特性，包括光谱带宽、时间相干性和信噪比 (SNR)。本研究为在调制不稳定性 (MI) 和受激拉曼散射 (SRS) 影响下的 CW 触发中红外 SC 提供了宝贵的见解。
