Abstract :
High efficiency continuous-wave operation of 1.53 μm vertical cavity surface emitting lasers (VCSELs) with buried tunnel junction grown by metal organic chemical vapour deposition (MOCVD) has been demonstrated. Devices show a high differential quantum efficiency of 46% and a singlemode power of 1 mW. Minimum threshold current and voltage are 0.45 mA and 1.3 V at room temperature, respectively for devices of 5 μm diameter.
