32 Gbit/s multimode fibre transmission using high-speed, low current density 850 nm VCSEL
Journal article, 2009
Error free transmission over multimode fibre at data rates up to 32 Gbit/s at 25C and 25 Gbit/s at 85C using an oxide confined 850 nm VCSEL biased at a current density of 11–14 kA/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.
