Abstract

High efficiency continuous wave operation of 1.53 μm vertical-cavity surface-emitting lasers (VCSELs) grown by metal organic chemical vapor deposition (MOCVD) has been demonstrated. Devices show a high differential quantum efficiency of 58% and a single-mode power of 1.38 mW with a side mode suppression ratio (SMSR) of 45 dB. Lasing wavelength is 1537 nm. Lasing operation up to 90° C has been achieved with 0.16 mW power at 85° C. A symmetric and narrow far field angle of less than 12° was observed. An error free transmission at 2.488 Gbps with a -26 dBm minimum average receiver power was demonstrated.
