Multi-level Optical Switching by Amorphization in Single- and Multi- Phase Change Material Structures
Simon Wredh, Yunzheng Wang, Joel K. W. Yang +1
The optical properties of phase-change materials (PCM) can be tuned to multiple levels by controlling the transition between their amorphous and crystalline phases. In multi-materi…
Capping Layer Effects on -based Reconfigurable Photonic Devices
Ting Yu Teo, Nanxi Li, Landobasa Y. M. Tobing +6
Capping layers are essential for protecting phase change materials (PCMs) used in non-volatile photonics technologies. This work demonstrates how caps r…
A biological approach to metalworking based on chitinous colloids and composites
Shiwei Ng, Benjamin Ng Guan Zhi, Robert E. Simpson +1
Biological systems evolve with minimum metabolic costs and use common components, and they represent guideposts toward a paradigm of manufacturing that is centered on minimum energ…
Low Thermal Conductivity Phase Change Memory Superlattices
Jing Ning, Xilin Zhou, Yunzheng Wang +6
Phase change memory devices are typically reset by melt-quenching a material to radically lower its electrical conductance. The high power and concomitantly high current density re…
Tunable wavefront control in the visible spectrum using low-loss chalcogenide phase change metasurfaces
Parikshit Moitra, Yunzheng Wang, Xinan Liang +6
All-dielectric metasurfaces provide unique solutions for advanced wavefront manipulation of light with complete control of amplitude and phase at sub-wavelength scales. One limitat…
Low energy switching of phase change materials using a 2D thermal boundary layer
Jing Ning, Yunzheng Wang, Ting Yu Teo +7
The switchable optical and electrical properties of phase change materials (PCMs) are finding new applications beyond data storage in reconfigurable photonic devices. However, high…
