| 摘 要： | High nonlinear microstructure fibre （HNMF） is preferred in nonlinear fibre optics, especially in the applications of optical parametric effects, due to its high optical nonlinear coefficient. However, polarization dependent dispersion will impact the nonlinear optical parametric process in HNMFs. In this paper, modulation instability （MI） method is used to measure the polarization dependent dispersion of a piece of commercial HNMF, including the group velocity dispersion, the dispersion slope, the fourth-order dispersion and group birefringence. It also experimentally demonstrates the impact of the polarization dependent dispersion on the continuous wave supercontinuum （SC） generation. On one axis MI sidebands with symmetric frequency detunings are generated, while on the other axis with larger MI frequency detuning, SC is generated by soliton self-frequency shift.

| Abstract: | High nonlinear microstructure fibre (HNMF) is preferred in nonlinear
fibre optics, especially in the applications of optical parametric
effects, due to its high optical nonlinear coefficient. However,
polarization dependent dispersion will impact the nonlinear optical
parametric process in HNMFs. In this paper, modulation instability
(MI) method is used to measure the polarization dependent dispersion
of a piece of commercial HNMF, including the group velocity
dispersion, the dispersion slope, the fourth-order dispersion and
group birefringence. It also experimentally demonstrates the impact
of the polarization dependent dispersion on the continuous wave
supercontinuum (SC) generation. On one axis MI sidebands with
symmetric frequency detunings are generated, while on the other axis
with larger MI frequency detuning, SC is generated by soliton
self-frequency shift. |
