High-Speed Oxide Confined 850-nm VCSELs Operating Error-Free at 40 Gb/s up to 85 degrees C

Artikel i vetenskaplig tidskrift, 2013

We present the temperature dependence of the performance characteristics of our latest generation high-speed oxide confined 850-nm vertical cavity surface-emitting lasers (VCSELs). Using a 7-mu m oxide aperture diameter VCSEL, we demonstrate a maximum modulation bandwidth of similar to 27 GHz at room temperature and similar to 21 GHz at 85 degrees C. With a new highspeed optical receiver, these bandwidths enable error-free data transmission ( defined as a bit-error-rate < 10(-12)) at bit-rates up to 47 Gb/s at room temperature, and up to 40 Gb/s at 85 degrees C.
