Low Eye-Skew Operations of 200-Gbps Directly Modulated 1060 nm Single-Mode VCSEL with Metal-Aperture Coupled Cavity

We demonstrate the low bias dependence of the small-signal response in our metal-aperture coupled-cavity VCSELs, enabling low eye-skew operation at 200 Gbps (PAM4) per lane, even with the use of a linear equalizer.
