ABSTRACT:
In a double heterojunction semiconductor laser, extremely high optical power density emission is achieved by forming a stripe-geometry exciting region in an active layer so as not to be exposed on the opposite reflective surfaces, and selecting a band gap of the stripe-geometry exciting region narrower than that of surrounding non-exciting region of the active layer. A pair of window regions formed between the respective reflective surfaces and the tip ends of the stripe-geometry exciting region are sandwiched between a pair of heterojunction interfaces and thus acting low loss optical waveguides. In addition, by providing an optical obstacle region in the vicinity of the window region, higher order modes in horizontal transverse mode oscillations are suppressed, and thereby extremely high optical power output at the fundamental mode can be obtained without causing catastrophic optical damage on the reflective surfaces.
