Towards the short-wavelength limit at 1450 nm in a widely tunable erbium-doped fiber laser

Abstract

We demonstrate a widely tunable fiber ring laser over 1451.9 similar to 1548.1 nm with temperature tuning efficiency as high as 57.3 nm/degrees C by using a 16-m-long standard silica-based erbium-doped fiber under 980-nm pump power of 208 mW. (C)2007 Optical Society of America
