利用具有正常平坦色散分布的As2Se3基多孔光纤（HF），分析了平坦宽带中红外超连续谱的产生。通过求解广义非线性薛定谔方程，数值模拟了不同参数下超短脉冲在高频中的传输。模拟结果表明，在波长为4375 nm，脉宽为50 fs，峰值功率为4.25 kW的脉冲入射到6 mm长的高频中，成功地产生了3 dB水平的平坦宽带超连续谱。超连续谱覆盖从3866到5958 nm的波长，这是在这样的短光纤中报道的最大平坦带宽。
By using an As2Se3based holey fiber (HF) with a normal flat dispersion profiles, a flattened and broadband mid-infrared super-continuum generation is analysed. The transmission of an ultra-short pulse in the HF is numerically simulated by solving the generalized nonlinear Schrödinger equation under various parameters. The simulation results show that, by launching a pulse with a width of 50 fs and a peak power of 4.25 kW at 4375 nm into the 6 mm-long HF, a flat and broadband super-continuum at 3 dB level is successfully generated. The super-continuum covers the wavelengths from 3866 to 5958 nm which is the largest flat bandwidth reported in such a short fiber.
