Abstract :
We have demonstrated electrically pumped operation at 1.55 /spl mu/m at room temperature of vertical-cavity lasers (VCLs) grown lattice-matched on InP. The VCLs present threshold currents lower than 10 mA. Powers around 10 mW and external quantum efficiencies of 38.3% have been measured.
