S+C+L ultra broadband light source research

摘要

Designed and implemented a new type of hybrid super-doped fiber fluorescent sources, Experiments using laser-diode-pumped erbium-doped fiber and Tm-doped fiber,Two 3dB couplers with broadband fiber reflector as,While taking advantage of the power control circuit for light stable light output, Get S + C + L-band ultra-bandwidth optical fiber light source. Received light power of 28 mW total, Bandwidth from 1460 nm to 1610 nm. The use of optical fiber loop mirror, Not only improved the flatness of the light source, And greatly improve the conversion efficiency of bare.
