摘　　要：We review the recent work of distributed-feedback （DFB） multi-wavelength semiconductor laser arrays （MWLAs） based on the reconstruction equivalent chirp （REC） technique. The experimental results show that the proposed MWLA has very high wavelength precision （〈 ± 0.1 nm）, while the fabrication cost is low. Only one step of holographic exposure and another step of photolithography are required for grating fabrication. The packaging technique for a high-bandwidth analog DFB laser and laser array was developed. A directly modulated MWLA transmitter module was achieved. In addition, an improved MWLA with an integrated reflector was proposed and successfully applied in a radio-over-fiber system.We review the recent work of distributed-feedback （DFB） multi-wavelength semiconductor laser arrays （MWLAs） based on the reconstruction equivalent chirp （REC） technique.
