Challenges in the Fabrication of Nanophotonic Integrated Circuits

Progress in the field of integrated photonics has been greatly accelerated by leveraging the existing microelectronics fabrication infrastructure. However, the fabrication of nanophotonic circuits carries a new set of challenges due to the high sensitivity of light–matter interactions. As the devices of integrated photonic circuits become smaller and more complex to satisfy increasing demands for performance, random errors and systematic inaccuracies in fabrication can cause significant reductions in real-world performance. In this lecture, we will discuss modern methods of fabricating photonic circuits, the challenges in fabricating next-generation designs, as well as current and near-future methods of overcoming these challenges.
