Paper Abstract

Energy efficient 200+ Gbit/s single fiber data transmission systems can be realized by wavelength multiplexing the directly modulated Vertical-Cavity Surface-Emitting Lasers (VCSELs) presented here, emitting at the four wavelengths 850 nm, 880 nm, 910 nm, and 940 nm. Large energy efficiency defined by a heat to data ratio (HBR) of only 240 fJ/bit @ 50 Gb/s is observed. Tuning the cavity photon lifetime is demonstrated to lead to an increase of the data rate in concert with a reduction of the HDR. The large linearity of our L-I-characteristics will allow easily higher order modulation rates. Our results might impact ongoing discussions of new physical layer standards for IEEE 802.3cm and cd coarse wavelength multiplexing standards across OM5 multimode fiber enabling up to 400 Gbit/s error-free transmission.
