Impact of Damping on 50 Gbps 4-PAM Modulation of 25G Class VCSELs

Not Accessible

Your library or personal account may give you access

Abstract

We investigate the effects of photon lifetime and damping of the modulation response on the quality of 50 Gbps 4-PAM signal generation with directly modulated 25G class VCSELs and identify the appropriate values for the K-factor.
