In this investigation, a convex-shaped fiber ring (CSFR)-based single-longitudinal-mode (SLM) erbium-doped fiber laser (EDFL) is proposed and experimentally verified. The CSFR, composed of only two optical couplers and forming a double-ring architect

Herein, we verify that a Raman/EDFA hybrid amplifier can improve the stability of fiber-optic time and frequency synchronization systems compared to the Er3+-doped fiber amplifier (EDFA), owing to its higher gain and lower noise figure (NF) performan

A dual-ring-architecture-based single-longitudinal-mode fiber laser with an ultranarrow linewidth of 610 Hz is proposed and experimental demonstrated. We achieved a lasing wavelength stabilization of less than 0.004 nm.

We propose a physical model of estimating noise and asymmetry brought by high isolation Bi-directional erbium-doped fiber amplifiers (Bi-EDFAs), no spontaneous lasing even with high gain, in longdistance fiber-optic time and frequency (T/F) synchroni

We introduce a fiber Brillouin amplifier (FBA) based on the use of orthogonal double pumps to overcome the fiber random birefringence effect which will reduces the gain and introduces the amplified signal power fluctuation in FBA. The signal with arb

In recent years, many researchers have focused on fiber Brillouin amplifier(FBA) for the higher amplify gain than traditional optical amplifiers, such as Erbium-doped fiber amplifier (EDFA). But the efficiency depends deeply on the relative state of
