Abstract

An increasing amount of high-bit rate applications such as video streaming and cloud computing more and more leads to a bandwidth bottleneck limitation in the world-wide telecommunication infrastructure [1]. Inside server centers, vertical-cavity surface-emitting lasers (VCSELs) are commonly used for short-haul optical data transmission. A maximum intensity modulation bandwidth of around 35 GHz (e.g. [2]) is currently achievable. However, reviewing the VCSEL development during the past years, the demand on bandwidth increases more rapidly than the available modulation bandwidth. Thus, alternative concepts are required.
