Abstract

Emerging passive optical networks (PONs) standards target 25Gb/s and 50Gb/s systems, requiring high optical powers without amplification. Externally modulated lasers (EMLs) yield low chirp. However, achieving output modulated power exceeding 10 dBm is challenging due to modulator insertion losses and saturation. In this invited presentation we will show our recent results in the development of EMLs based on semi-insulating buried heterostructure (SIBH) waveguide. We will present the main EML design rules and compromises, then apply them to different EMLs aiming at major telecom and datacom applications, with special focus on novel devices addressing the needs of emerging PON applications.
