850nm VCSELs for 10Gb/s operation

Summary form only given. 850nm VCSELs are finding escalating markets in fiber optical communication applications, such as 10Gbit-Ethenet, OC-192 VSR and so on. It offers significant advantages for realizing cost-effective, high speed data links. Our progress towards achieving 10Gb/s VCSEL is reviewed. In this report, we investigated the optimization of oxide aperture size for 10Gb/s operation. And also, we demonstrated the 10Gb/s transmission over 100m of standard GI-50 multi-mode fiber. We fabricated 850nm VCSELs with an oxide layer for current and optical confinement, providing low threshold current, low driving voltage, and high speed operation.
