Variable and stable dual-wavelength erbium-doped fiber laser based on fiber acousto-optic variable filter and highly nonlinear fiber

摘要

A dual-wavelength erbium-doped fiber (EDF) variable ring laser using a fiber acousto-optic tunable filter (AOTF) and highly nonlinear fiber (HNLF) is demonstrated. Stable and variable lasing wavelengths were achieved by electronically adjusting the AOTF settings.
