All Polarization Maintaining Brillouin Erbium-Doped Fiber Laser With Sub-kHz Linewidth Using Saturated Absorber and Self-Injection Feedback

IEEE Photonics Journal
A narrow-linewidth all-polarization-maintaining (PM) Brillouin erbium-doped fiber laser (BEFL) is proposed and demonstrated experimentally, which employs erbium-doped fiber (EDF) acting as both the linear gain and the Brillouin gain medium.

Regulating emission in Er doped silicate glass and fiber via coordination engineering

Journal of Materiomics
L-band Er doped fiber (EDF) laser sources are in great demand for extending communication bandwidth. However, the gain performance is limited by the low emission cross section (σe) of Er3+ at wavelengths longer than 1590 nm. In our study, we revealed the

Tunable Narrow Linewidth Erbium-Doped Fiber Ring Laser Based on Saturable Absorber and Self-Injection Feedback

IEEE Photonics Journal
We demonstrate a tunable single-longitudinal-mode (SLM) narrow linewidth erbium-doped fiber (EDF) ring laser (EDFRL) in a cost-effective way. The laser incorporates an unpumped-EDF-based saturable absorber (SA) and a self-injection feedback loop for mode
