Abstract

Wavelength switching in a mutually injection-locked erbium-doped fiber ring laser and distributed-feedback laser diode (DFBLD) is experimentally demonstrated. By adjusting the power and the polarization state of injected light, three stable oscillation regimes were observed: Fabry-Pérot (FP) mode oscillation, main distributed-feedback (DFB) mode oscillation, and dual-wavelength oscillation. Wavelength switching of 0.8 nm from one of the FP oscillation modes to the main DFB mode of the DFBLD is accomplished when the bias current to the DFBLD is varied from 9 to 14 mA. We also show that these wavelengths can be tuned as much as 2.48 nm when the temperature of the DFBLD is changed by 20 °C.
