As the bit rates of high-speed data transmission increase, the dynamic properties of the VCSEL are becoming more important. High photon density is of great importance for high modulation efficiency and low noise. We will present a schematic of the Zarlink 850nm 10Gb/s selectively oxidized VCSEL design and results from small and large signal modulation. The modulation characteristics were improved by utilizing InGaAs quantum wells, which have better gain characteristics than GaAs wells. 10Gb/s transmission over 300m of OFS-Fitel LaserWave<SUP>tm</SUP> 300 Fiber for a 12micrometers aperture multimode VCSEL at 80 degree(s)C will be demonstrated. Bit error rate (BER) measurement with the corresponding power penalty will also be presented.
