Abstract :
Energy-efficient oxide-confined 850 nm vertical-cavity surface-emitting lasers (VCSELs) for optical interconnects are presented. Error-free data transmission at 40 Gbit/s is achieved with a record low dissipated heat per bit (energy efficiency) of only 108 fJ/bit. At 36 Gbit/s across 200 m and at 40 Gbit/s across 50 m of OM3 plus multimode optical fibre error-free operation is achieved with energy efficiencies of 127 and 119 fJ/bit, respectively.
