1.02 /spl mu/m vertical-cavity surface-emitting lasers for perfluorinated graded index POF communications

In this paper, we demonstrate the VCSEL operating at 1.02 /spl mu/m for perfluorinated graded-index plastic optical fiber communication (POF) applications. The VCSEL is grown by solid-source molecular beam epitaxy. The VCSELs operate in cw mode up to chip temperature of 80/spl deg/C. And the threshold current is 6.1 mA at room-temperature, corresponding to a threshold current density of 1.8 kA/cm/sup 2/ per quantum well. The output power is 0.7 mW at 14-mA drive current.
