Abstract
Emcore's 850 nm UltralaseTM VCSELs, operating at a data rate from 1 Gb/s to 25 Gb/s, is presented. They were based on our low-cost and hermetic-by-design chip platform which contains the same element for either singlets or arrays with a 250 μm pitch. First, we discuss high-speed VCSEL evolutions, device designs, manufacturing processes, and device characteristics. Secondly, we present performance of Emcore's TOSAs, 40 Gb/s parallel optic modules (S12), 120 Gb/s CXP modules, active connect cables (40 Gb/s QDR and 56 Gb/s FDR), as well as comprehensive reliability qualifications of UltralaseTM VCSELs. Lastly, we briefly go over the recent progress of 20 Gb/s and 25 Gb/s VCSEL developments. We have successfully achieved a 3dB bandwidth of 15 GHz at 85°C and 8 mA for a 7.5 μm aperture UltralaseTM VCSEL.
