Abstract A quantum well laser and its Schottky barrier contact method for limiting current is disclosed. Said schottky contact barrier is prepared through magnetically controlled sputtering to sputter Ti/Pt/Au contact electrode and schottky contact gold, optical and chemical etching to form laser waveguide metal strips at intervals, chemical corrosion to remove GaAs layer between metal strips and expose InGaP layer, cleaning and sputtering gold.
