More Information
Summary:A distributed feedback (DFB) laser array includes a substrate, a semiconductor stacked structure, a first electrode layer, and a second electrode layer. The semiconductor stacked structure is formed above a surface of the substrate and includes two light-emitting modules and a tunnel junction. Each light-emitting module of the two light-emitting modules includes an active layer, a first cladding layer, and a second cladding layer. The active layer is installed between the first cladding layer and the second cladding layer, and the active layer has multiple lasing spots along a first direction, wherein the multiple lasing spots are used for generating multiple lasers. The tunnel junction is installed between the two light-emitting modules. The first electrode layer is formed above the semiconductor stacked structure. The second electrode layer is formed above another surface of the substrate.
