  • Abstract
    Error free transmission over multimode fibre at data rates up to 3 2 Gbit/s at 25degC and 25 Gbit/s at 85degC using an oxide confined 850 nm VCSEL biased at a current density of 11-14kA/cm2 is demonstrated. The VCSEL is optimised for high-speed by reducing capacitance and self-heating and by using strained InGaAs quantum wells for high differential gain.
