Paper Abstract

Higher speed VCSELs at different wavelengths and adapted to different modulation formats are needed to meet demands for higher optical interconnect capacity and bandwidth density. We discuss VCSEL dynamics and speed limitations, recent progress on high-speed VCSELs from 850 to 1060 nm, and less conventional VCSEL designs for potentially more significant speed improvements. We also discuss the interconnect capacity enabled by equalization, pulse shaping, higher order modulation formats, digital signal processing, and wavelength division multiplexing.
