摘要: Abstract Multi-wavelength erbium-doped fiber laser (EDFL) is of significant interest due to its operation within the conventional optical communication band. The primary concern in multi-wavelength EDFL low stability gain medium room temperature. This work proposed use graphene-polymethyl methacrylate (PMMA) thin film as a stabilizer and nonlinear generate stable EDFL. Six channels with constant spacing 0.62 nm are observed 10 dB peak power difference. these lasers measured at less than 0.8 dB an observation time 300 min. These findings validate potential graphene/PMMA key element producing simple highly structure.
