Join us for this PSI seminar with guest speaker Prof. Robert Simpson. The objective of this seminar is to highlight that new materials need to be developed specifically for programmable metamaterials. The inherent property portfolios of the common telluride phase change materials, which have been successfully applied in data storage technologies, are unsuitable for most emerging programmable photonics applications. We believe that newer PCMs with wider bandgaps, such as Sb2S3, Sb2Se3, and Ge2Sb2Se4Te (GSST), can be optimized to meet the demands of holographic displays, optical neural network memories, and beam steering devices.
Prof. Simpson will start the seminar by discussing the history of phase change materials and their application to photonics. He will then discuss the suitability of the materials we have used to enable visible, near-infrared, and mid-infrared programmable metamaterials. Finally, Prof. Simpson will discuss his plans for his new position at the University of Birmingham.

Biography: Robert E. Simpson is an Associate Professor in the School of Engineering at the University of Birmingham. Robert received his PhD from the Optoelectronics Research Centre (ORC) at the University of Southampton in the UK in 2008. After his PhD, Robert was awarded Marie Curie and Japanese Society for the Promotion of Science (JSPS) fellowships. His JSPS fellowship was spent at the Japanese National Institute for Applied Industrial Science and Technology (AIST), where Robert researched phase change data storage materials. The Marie Curie fellowship was held at the Institute of Photonic Sciences (ICFO) in Barcelona, where he developed phase change material-tuneable photonics devices. In 2012, Robert formed the Advanced Chalcogenides Technologies & Applications Lab (www.actalab.com) at the Singapore University of Technology and Design (SUTD).
