Photonic Integrated Circuit (PIC) technology has revolutionized the application and fabrication of optoelectronic devices. Most affected by this development is the field of telecommunications, where both active and passive photonic devices are key components in the optical networks. PIC based optical components are cheaper to fabricate than their stand-alone counter parts, multifunctional, low energy consumers and much smaller in size. These qualities make PICs very attractive from a mass-integration point of view and they are generally viewed as the successors of electronic ICs. Light-matter interaction in semiconductor materials involves several timescales and the interplay between these timescales is one of the main causes of the unpredictable nonlinear dynamics that opto-electronic devices are known to exhibit [1]. Due to the small distances on PICs, it was generally assumed that the various timescales will equalize and that they will exhibit less nonlinear dynamics than their stand-alone counter parts. Indeed, the decrease in size made fewer modes of operation available, but the decrease in losses and the closeness of the components on a PIC allowed for much stronger coupling between components and the nonlinear dynamics remained in a large parameter range.
