Inverse designed resistive heaters for uniform switching of Phase Change Materials
Virat Tara, Khoi P. Dao, Juejun Hu +1
Non-volatile phase-change material (PCM)-integrated metasurfaces offer a promising pathway toward next-generation solid-state reconfigurable free-space optics. However, their pract…
Wafer-scale conformal metasurface optics
Louis Martin-Monier, Sehui Chang, Johannes Froech +11
Curved and conformal optics offer significant advantages by unlocking additional geometric degrees of freedom for optical design. These capabilities enable enhanced optical perform…
2D Addressable Mid-infrared Metasurface Spatial Light Modulator
Cosmin-Constantin Popescu, Maarten Robbert Anton Peters, Oleg Maksimov +12
Active metasurfaces enable dynamic control of light for applications in beam steering, pixelated holography, and adaptive optics, but demonstrations of two-dimensional (2D) electri…
Unravelling and circumventing failure mechanisms in chalcogenide optical phase change materials
Cosmin Constantin Popescu, Kiumars Aryana, Brian Mills +17
Chalcogenide optical phase change materials (PCMs) have garnered significant interest for their growing applications in programmable photonics, optical analog computing, active met…
Design of an ultra-compact, energy-efficient non-volatile photonic switch based on phase change materials
Khoi Phuong Dao, Juejun Hu, Richard Soref
The on-chip photonic switch is a critical building block for photonic integrated circuits (PICs) and the integration of phase change materials (PCMs) enables non-volatile switch de…
