Fabry-Perot laser (FP-LD) is the most common semiconductor laser. At present, the fabrication technology of FP-LD used in optical fiber communication has been quite mature, and the structure of double heterojunction multiple quantum wells active layer, carrier and light limited structure is widely used.
