Energy-efficient 1.3 #x03BC;m short-cavity VCSELs for 30 Gb/s error-free optical links

摘要

We present the first error-free data-transmission at 30 Gb/s over up to 10 km of fiber using energy-efficient 1.3 μm short-cavity VCSELs with low threshold current of 500 μA and high conversion efficiencies up to 30%. A record-low energy-to-data-distance ratio of 27 fJ/(bit·km) is achieved for such a VCSEL-link.
