Abstract

Complex oxides such as perovskite semiconductors possess electronic structures that are highly tunable via external stimuli. The phase switching can be volatile (threshold switches) or non-volatile (memory / synaptic). I will present an overview of correlated oxide systems where one can create sub-wavelength dielectric environments on-demand exploiting metal-insulator transitions. We will discuss use cases in analog photonic computing, meta-X devices and microwave technologies. The role of materials synthesis, defects and their influence in photonic device performance will be discussed.
