Abstract

An erbium-doped fiber (EDF) laser with quad-ring is designed to reach the broad continuouswave (CW) tunability and single-longitudinal-mode (SLM) behavior. Here, while a C-band erbiumbased gain medium is exploited, the tunable scope can be extended from C-to part of L-bands and narrow the linewidth to several kHz by the presented compound-ring configuration. Additionally, the optical signal to noise ratio (OSNR), output power, and stability behavior of every lasing wavelength are also demonstrated.
