50 Gb/s 850 nm Few-Mode VCSELs for Pre-Emphasis NRZ-OOK over 100-m GI-SMF Transmission

Abstract

A few-mode VCSEL has an oxide-confined aperture of 6 µm and a heavily Zn-diffusion aperture of 4 µm, which is demonstrated a -3-dB E-O bandwidth (26.5 GHz), and passed 50 Gb/s pre-emphasis NRZ-OOK transmission over 100 m GI-SMF links.
