Abstract

A triple-wavelength erbium-doped fiber laser based on seven-core fiber (SCF) interferometer is proposed and successfully implemented. In the structure of the laser, a special structure of single-seven-single core is used to realize laser interference, which is composed of a 6 cm SCF and ordinary fiber optic patch cables fused by convex cone. In the laser with simple structure, triple-wavelength output with central wavelengths of 1530 nm, 1544 nm and 1558 nm are obtained by adjusting the polarization controller, and the optical signal-to-noise ratio (OSNR) of the triple-wavelengths is approximately 60 dB. The laser has high stability in terms of both wavelength and power. In the stability test of 150 min, the frequency drift of three wavelengths is approximately 0.4 nm, and the output wavelength peak power jitter is approximately 1.6 dB. The laser has the characteristics of simple structure and high stability, and has broad application prospects in the fields of optical fiber sensing, wavelength division multiplexing (WDM) optical communication system and microwave photonics.
