Abstract

In this paper, we report the development of an Er3-doped dual-wavelength fiber laser constructed from a quasi-ring structure incorporated with two cascaded fiber Bragg gratings (FBGs). A total output power of 8.5 dBm and a mode suppression ratio of more than 50 dB have been obtained in the cw operation case. The mode competition phenomenon for dual wavelengths lasing has been investigated by reducing the wavelength spacing of the two FBGs. With mode locking, switching from one wavelength to the other, and between single- and dual- wavelength lasing has been demonstrated by adjusting the rf frequency of an intensity modulator in the laser cavity.
