Intrinsic Limitations of Single Layer Polychromatic Metalens for Virtual Reality Visors
Myunghoo Lee, Ben Nguyen, Zhihao Zhou +7
Virtual and augmented reality (VR/AR) visors require compact and lightweight optics. Metalenses have been widely proposed as ultrathin replacements for bulky refractive eyepieces,…
Complex wavefront engineering via decoupled space-time modulation
Virat Tara, Anna Wirth-Singh, Johannes E. Fröch +1
Solid-state Spatial Light Modulators (SLMs) are fundamentally limited in their ability to achieve high spatial complexity and high temporal bandwidth simultaneously. High-speed, lo…
Advantages of Broadband Metalenses for Generalizable Image Classification
Yubo Zhang, Johannes Fröch, Jinlin Xiang +6
Optical neural networks (ONNs) are gaining increasing attention to accelerate machine learning tasks. In particular, static meta-optical encoders designed for task-specific pre-pro…
Electrically reconfigurable nonvolatile transmissive metasurface in visible
Virat Tara, Romil Audhkhasi, Andrew Tang +5
The synergy between metasurfaces and non-volatile phase change materials (PCMs) has created many reconfigurable photonic devices for applications in optical memory, optical computi…
