Abstract :
A novel technique for extraction of diode laser parameters is demonstrated. With tunable vertical cavity surface emitting lasers (VCSELs), the internal quantum efficiency, internal loss, average gain coefficient, and transparent current density can be extracted on the same device. This technique enables evaluation of critical elements and design of VCSEL structures
