Abstract
We demonstrate a new structure for long-wavelength (1.3-mu m) vertical -cavity top-surface-emitting lasers using proton implantation for curr ent confinement, Wafer-bonded GaAs-AlAs Bragg mirrors and dielectric m irrors are used for bottom and top mirrors, respectively, The gain med ium of the lasers consists of nine strain-compensated AlGaInAs quantum wells, A record low room temperature pulsed threshold current density of 1.13 kA/cm(2) has been achieved for 15-mu m diameter devices with a threshold current of 2 mA, The side-mode-suppression-ratio is greate r than 35 dB.
