Oxide materials are widely used in photonic devices. Recently, with the development of photonic integrated circuits (PICs), planar integration of oxide thin film materials and photonic devices has become an actively studied emerging field. In this feature issue, we present 12 papers in the field of planar oxide photonics. Topics include passive and active photonic devices based on oxide materials for applications in a variety of planar integrated photonic devices such as metasurfaces, optical isolators, photodetectors, modulators, light sources and nonlinear photonics.
