We report 12.5 Gbit/s data transmission over 100 m multimode fiber (MMF) and 1 km single-mode fiber (SMF) using single-mode selectively oxidized GaAs VCSELs emitting at 850 nm. In both cases the bit-error rate (BER) remains better than 10/sup -11/ for pseudo-random bit sequence (PRBS) transmission. The obtained results clearly indicate that GaAs VCSELs are attractive transmitters for high speed fiber optic interconnects. A schematic of the selectively oxidized top emitting GaAs VCSEL is shown-the one-wavelength thick inner cavity contains three active GaAs-Al/sub 0.2/Ga/sub 0.8/As quantum wells.
