Message: CST Global to present paper on high speed 850nm VCSELs
7th June 2017
VCSEL aperture size can enable modulation bandwidths of up to 27GHz with data transmission rates of up to 50Gb/s
UK-based III-V foundry CST Global (a subsidiary of Sivers IMA), will be presenting a paper at the VCSEL Conference, 8th and 9th June 2017, in Cardiff, demonstrating how data transmission rates of 50Gb/s can be achieved with 850nm VCSELs.
VCSELs offer a high bandwidth, power-saving and low-cost solution for the Active Optical Cable (AOC) links used within next-generation, datacentres and high-performance computing.
“The VCSELs and GaAs PIN photo-diodes used in AOCs must deliver 50Gb/s or more, to meet anticipated demand. We have designed and fabricated new 850nm VCSELs and photo-detectors with low capacitance for high-speed operation. We have then, successfully, demonstrated how VCSEL aperture size can enable modulation bandwidths of up to 27GHz with data transmission rates of up to 50Gb/s,” explains project engineer, Iain Eddie, who will be presenting the white paper.
Eddie's paper provides a summary report for the ADDAPT project (Adaptive Data and Power Aware Transceivers for Optical Communications), a Seventh Framework Programme (FP7) funded by the European Commission. This project seeks to combine the complementary competences of two universities and three commercial organisations, including device manufacture by CST Global.
