Abstract

In this presentation, we demonstrate an erbium-doped fiber (EDF) laser by a compound-ring structure to reach the output performances of narrow linewidth, stable single-longitudinal-mode (SLM) and high optical signal to noise ratio (OSNR) in the L-band bandwidth of 1563.0 to 1613.0 nm. Based on the Vernier effect through the compound-ring design, the substantial multi-longitudinal-mode (MLM) noises can be mitigated fully. Furthermore, the relative optical output features of the fiber laser are also performed experimentally.
