Abstract :
A GaAs-AlxGa1-xAs strip buried heterostructure laser with distributed feedback Bragg reflectors is described. In this structure, the active strip is present in the form of an isolated segment completely buried in wide band gap AlxGa1-xAs. The diode is shown to operate stably in single transverse (fundamental) and longitudinal modes when the Fabry-Perot modes are suppressed by saw cutting the mirrors.
