Abstract :
Theoretical and experimental analysis of carrier transport in high-performance 1300-nm InGaAsN QW lasers, indicate significant thermionic hole leakage. Experimental optimization of the InGaAsN QW lasers by suppressing the carrier leakage, results in an extremely-low threshold current density of only 440 A/cm/sup 2/ at temperatures of 90/spl deg/C.
