Wavelength switchable mode-locked Erbium-doped fiber laser based on monolayer graphene

Abstract

We generate simultaneously polarization-depend mode-locked Erbium-doped fiber laser based on monolayer graphene at 1557-nm band and 1536-nm with a spectral width of 10.2-nm and 8.2-nm respectively and spectral width of 5.7-nm for the same bands in dual-band configuration.
