Vector mode inter-modal wavelength conversion in a dispersion tailored highly nonlinear few-mode fibre

摘要

We present the design and fabrication of a dispersion tailored highly nonlinear few-mode fibre with an inter-modal nonlinear coefficient of 2.81 (W · km)⁻¹, the highest reported to date. Inter-modal wavelength conversion between the HE21 and TE01 vector modes is demonstrated in the fibre.
