Design of laser array light source module based on REC technology
In recent years, monolithic integrated multi wavelength laser array(MLA) has become a hot research topic, as an ideal light source in the wavelength division multiplexing system. A low-cost distributed-feedback(DFB) laser array light source module based on reconstruction-equivalent-chirp(REC) technology was demonstrated. The output of this module was amplified by Erbium-doped fiber amplifier (EDFA) and adjusted by PID control program. The center wavelength spacing of the light source module was uniform. The average interval was 1.64 nm, and the wavelength spacing deviation was less than 0.2 nm. The total output power of the light source was more than 50 mW and the output light power change was less than 0.02 dBm.
