Photonic Integrated Circuits allow miniaturizing photonic systems used in numerous fields of application. We will describe the different existing technologies to integrate photonic systems, including silicon and indium phosphide, covering the advantages and disadvantages. The course then will introduce the different building blocks, passive and active, describing their basic parameters, and the technological limitations for each. This basic building blocks allow to develop some basic components, such as DFB and DBR lasers, from which photonic systems grow. The course takes the bottom-up approach, describing first the basic components to reach the system. Real examples of photonic integrated circuits will be presented, such as optical interconnects and wireless transceivers. We will also introduce specific tools for design.
