Emerging Materials for Light Emission and Non-volatile Photonic Memories

This interdisciplinary symposium aims to deepen the mechanistic understanding of light emission in novel material platforms, as well as emerging materials and devices for reconfigurable zero-power integrated photonic memory elements. The first part of this special session will focus on new light-emitting materials with emphasis on perovskite nanocrystals, which have demonstrated exceptionally high luminescence yields. Aspects covered range from fundamental photophysics and the synthesis of novel materials beyond the APbX3 prototype to understanding and optimizing application-driven properties for lighting and quantum communication. The second part of this session is dedicated to phase-change materials that exhibit distinct optical properties between their crystalline and amorphous states, maintained in a non-volatile manner. Emerging compounds such as Sb2S3, achieving broadband transparent operation for scalable integrated circuitry, and GeTe, featuring resonant wavelength-selective absorption, are featured. Phase-change materials already are a mature technology for optical storage. Recently advances have shown initial integration on photonic waveguides with multi-level operation, optical or electrical switching, or configured in resonant absorber optical metasurfaces for non-volatile color filtering or reflectance in free-space optics. This interdisciplinary symposium aims to stimulate new research at the intersection of emerging optoelectronic and photonic materials, ranging from perovskite nanocrystals typically used for LED applications to phase-change materials for non-volatile photonic memories.
