In this paper both statistic and dynamic behaviors of the multimode fiber Bragg grating external cavity lasers (MMFBG_ECL) have been studied experimentally, and simulated numerically by time domain traveling wave (TDTW) rate equations. Experimentally, multiple wavelength selection has been realized by offsetting the coupling between the laser diode (LD) and the MMFBG. Small signal modulation responses at these wavelengths have been measured and over 8 GHz modulation bandwidths have been demonstrated at several wavelengths. Numerically, the TDTW model has been employed to simulate the multiple wavelength lasing selection and L-I curves. Comparison between single mode fiber Bragg grating external cavity lasers (SMFBG-ECL) and MMFBG-ECL have been addressed. In addition, steady experiments and numerical simulated are made to verify our numerical model.
