摘要

Over the past two decades, photonic inverse design has emerged as a powerful approach to implement photonic devices with improved performance or to realize new functionalities. Whereas the efforts over the first decade focused on proof-of-concept devices designed and fabricated in university laboratories, the focus over the past 5–10 years has shifted towards implementation of scalable photonic systems. This Review surveys this recent progress and the challenges and new directions in photonics inverse design. We focus on large-scale 3D photonic inverse design, including metasurfaces, on the translation of inverse design to commercial foundries and practical silicon photonics, on the application of photonic inverse design to different materials systems, wavelengths and optical effects and, finally, on new directions such as inverse design of quantum systems.
