Low operating current and high temperature operation of 650 nm AlGaInP high power laser diodes with real refractive index guided self-aligned structure

Low operating current and high temperature operation has been achieved in 650 nm AlGaInP high power double quantum well laser diodes with a real refractive index guided self-aligned (RISA) structure. The attained operating current for 50 mW CW at 70/spl deg/C is as low as 98 mA, which is almost a half of the lowest value ever reported.
