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…
Tunable Mie Resonances in the Visible Spectrum
Li Lu, Zhaogang Dong, Febiana Tijiptoharsono +7
Dielectric optical nanoantennas play an important role in color displays, metasurface holograms, and wavefront shaping applications. They usually exploit Mie resonances as supporte…
A scheme for simulating multi-level phase change photonics materials
Yunzheng Wang, Jing Ning, Li Lu +2
Chalcogenide phase change materials (PCMs) have been extensively applied in data storage, and they are now being proposed for high resolution displays, holographic displays, reprog…
A comparison of phase change materials in reconfigurable silicon photonic directional couplers
Ting Yu Teo, Milos Krbal, Jan Mistrik +3
The unique optical properties of phase change materials (PCMs) can be exploited to develop efficient reconfigurable photonic devices. Here, we design, model, and compare the perfor…
Wide band gap phase change material tuned visible photonics
Weiling Dong, Hailong Liu, Jitendra K Behera +6
Light strongly interacts with structures that are of a similar scale to its wavelength; typically nanoscale features for light in the visible spectrum. However, the optical respons…
Inter-diffusion of Plasmonic Metals and Phase Change Materials
Li Lu, Weiling Dong, Jitendra K. Behera +2
This work investigates the problematic diffusion of metal atoms into phase change chalcogenides, which can destroy resonances in photonic devices. Interfaces between Ge2Sb2Te5 and…
