200Gb/s PAM4 oxide VCSEL development progress at Broadcom
The connectivity demands of high performance computing (HPC), artificial intelligence (AI) and data centers is driving the development of a new generation of multimode optical components. This paper will discuss the vertical cavity surface emitting laser (VCSEL) bandwidth and noise performance needed to support 106 Gbd line rates with PAM-4 modulation for 200Gb/s per lane multimode optical links. VCSEL device performance and associated wear out life will be presented.
