Abstract

In the last few years, all-optical signal processing based on 2D materials has been a hot topic because of its ultra-fast optical response, broadband optical absorption, and tunable optoelectronic characteristics. However, there are few reports about all-optical wavelength conversion concentrate on the 2μm communication band in the existing research for the limits of small nonlinear coefficient, serious linear and nonlinear loss, or small conversion bandwidth. In our work, four-wave mixing in the 2μm band is realized by fabricating graphene modified micro/nano optical fiber devices, which can achieve the -46.21dB wavelength conversion efficiency. This work will contribute to the practical application of 2μm band wavelength conversion.
