研究目的
Investigating the efficient supercontinuum generation in highly nonlinear dispersion-shifted fiber triggered by a weak 100-kHz linewidth continuous-wave seed.
研究成果
The study demonstrates that a narrow linewidth CW seed can significantly enhance supercontinuum generation through strong four-wave mixing effects, achieving spectral modification at a very low power level (10-7 relative to pump), with good agreement between experimental and numerical results.
研究不足
Deviations in simulation results due to simplified dispersion parameters (only β2 and β3 considered) and nonlinearity in transmission fibers; spectrum broadening of pump pulse before coupling into HNL-DSF.
1：Experimental Design and Method Selection:
The experiment is designed to study supercontinuum generation using a picosecond pulse pump and a weak continuous-wave seed in a highly nonlinear dispersion-shifted fiber. The generalized nonlinear Schr?dinger equation is used for numerical simulation.
2：Sample Selection and Data Sources:
A
3：5-meter highly nonlinear dispersion-shifted fiber is used as the sample. Data is collected from optical spectrum measurements. List of Experimental Equipment and Materials:
Includes a mode-locked fiber laser, Er:Yb co-doped fiber amplifier, tunable fiber laser (TSL-710, Santec), 10/90 high power fiber coupler, HNL-DSF fiber, optical spectrum analyzer (AQ6370D, Yokogawa), and power meter (S148C, Thorlabs).
4：Experimental Procedures and Operational Workflow:
The pump pulse and CW seed are combined and launched into the fiber. Output spectra and power are measured with varying CW wavelengths and powers.
5：Data Analysis Methods:
Spectra are analyzed using the optical spectrum analyzer, and numerical simulations are performed based on the GNLSE.
