Abstract
A semiconductor laser having a mesa structure includes active laser layers. The mesa structure is confined by Fe—InP lateral semi-insulating layers. A p blocking layer is interposed between the mesa structure and the lateral semi-insulating layers. Performance at high temperature and linear laser operation are improved. A preferred application is for manufacturing SIBH-DFB lasers for direct modulation in the 10 Gbit/s range.
