WebDec 10, 2014 · VCSEL arrays are distinctly different from the world of conventional high-power laser diodes. The latter is dominated by lasers for cutting or welding steel, where it is all about what laser system has the highest brightness and power to cut even faster through even thicker steel. Webthe VCSEL driver output stage, described in detail in [1]; it con-sists of a 4-tap current-mode FIR filter that equalizes the VCSEL response at high data rates. At the receiver side, a low-voltage integrating and double-sampling front-end performs demulti-plexing directly at the input node using 5 uniform clock phases
