VCSEL-based optical transceivers in data centers meet the increase in data traffic by increasing the data transmission rate. A single-channel PAM-4 data rate of >100 Gb/s is already in high demand. For 100Gb/s operation a low relative intensity noise (RIN) significantly gains importance. The challenge is to reduce the RIN without impeding the other static and dynamic VCSEL performance parameters. We demonstrate up to 20 dB/Hz RIN reduction of commercial VCSELs that are approaching the shot noise limit and give an outlook on datacom VCSELs for higher order modulation formats for single channel data rates of 100 Gb/s and beyond.
