Electrically reconfigurable phase-change transmissive metasurface
Cosmin Constantin Popescu, Kiumars Aryana, Parth Garud +12
Programmable and reconfigurable optics hold significant potential for transforming a broad spectrum of applications, spanning space explorations to biomedical imaging, gas sensing,…
Ruddlesden-Popper chalcogenides push the limit of mechanical stiffness and glass-like thermal conductivity in single crystals
Md Shafkat Bin Hoque, Eric R. Hoglund, Boyang Zhao +20
Insulating materials featuring ultralow thermal conductivity for diverse applications also require robust mechanical properties. Conventional thinking, however, which correlates st…
Versatile spaceborne photonics with chalcogenide phase-change materials
Hyun Jung Kim, Matthew Julian, Calum Williams +6
Recent growth in space systems has seen increasing capabilities packed into smaller and lighter Earth observation and deep space mission spacecraft. Phase-change materials (PCMs) a…
An Open-Source Multi-functional Testing Platform for Optical Phase Change Materials
Cosmin-Constantin Popescu, Khoi Phuong Dao, Luigi Ranno +18
Owing to their unique tunable optical properties, chalcogenide phase change materials are increasingly being investigated for optics and photonics applications. However, in situ ch…
Toward accurate thermal modeling of phase change material based photonic devices
Kiumars Aryana, Hyun Jung Kim, Cosmin-Constantin Popescu +5
Reconfigurable or programmable photonic devices are rapidly growing and have become an integral part of many optical systems. The ability to selectively modulate electromagnetic wa…
