“…Supercontinuum generation (SCG) performance is strongly influenced by the dispersion profile of the PCF. When the input pulse is pumped in the anomalous dispersion regime, stimulated Raman scattering 7 , including soliton fission (SF) and soliton self-frequency shift (SSFS), is the key nonlinear effect responsible for the quality of the SCG spectrum. However, the presence of solitons causes the spectrum to be noisy.…”

Introduction:In this study, we report a new design of a circular lattice photonic crystal fiber and investigate its optical properties numerically. Methods: Near-zero ultra-flattened chromatic dispersion is achieved by allowing benzene (C 6 H 6 ) to infiltrate the hollow core and induce a difference in the air hole size in the cladding. By solving Maxwell's wave equations using the full-vector finitedifference eigenmode, the electromagnetic field modes are analyzed. Results: The results show that the variation in dispersion over the broad wavelength range of 527 nm is ± 0.753 ps/nm.km. The nonlinearity coefficient is significantly improved with a value of several thousands W −1 .km −1, which is favorable for supercontinuum generation with low input power even though the confinement loss has not yet reached its desired value. Conclusion: Two PCFs with optimal lattice parameters and suitable characteristic quantities are selected for supercontinuum generation orientation compatible with application fields such as spectroscopy, temperature sensing, and telecommunication.
