“…A stable and wavelength-selectable erbium-doped fiber (EDF) ring laser is an attractive light source for applications such as optical fiber sensing, optical testing, microwave photonics, wavelength-division-multiplexing (WDM) transmission, and optical instrument testing [1][2][3][4]. Generally, in order to accomplish the wavelength lasing and tuning, the fiber Fabry-Perot tunable filter (FP-TF), tunable bandpass filter (TBF), and variable fiber Bragg grating (FBG) have been proposed and utilized inside the fiber-loop cavity [5][6][7]. Due to the modehopping and homogeneous broadening of EDF, it would result in the unstable and densely multi-longitudinal-mode (MLM) wavelength output [8].…”

In this paper, a stable and wavelength-switchable silicon-photonic erbium-doped fiber (EDF) triple-ring laser is proposed and demonstrated. In the experiment, the integration of a silicon-on-insulator (SOI)-based grating coupler and silicon-micro-ring-resonator (SMRR) are coupled and connected to the proposed EDF triple-ring laser for generating wavelength. Here, the output wavelength can be adjusted in a wavelength range of 1529.8 –1561.8 nm with a 2.0 nm tuning step according to the free spectrum range (FSR) of the SMRR. Moreover, the stability performance of the output power and wavelength are also discussed and analyzed.
