Performance characteristics and extended lifetime data for InGaAsP/InP LED's

The performance and lifetest results of InGaAsP/InP LED's emitting at 1.27 µm are described. At a current density of 10 kA/cm
²
, 40 µW of optical power is coupled into a 63 µm core, 0.21 NA optical fiber, and the projected lifetime at room temperature is approximately estimated to be 8 × 10
