Electrically Reconfigurable Nonvolatile Metasurface Using Low-Loss Optical Phase Change Material
Yifei Zhang, Clayton Fowler, Junhao Liang +14
Active metasurfaces promise reconfigurable optics with drastically improved compactness, ruggedness, manufacturability, and functionality compared to their traditional bulk counter…
Multi-level Electro-thermal Switching of Optical Phase-Change Materials Using Graphene
Carlos Ríos, Yifei Zhang, Mikhail Shalaginov +13
Reconfigurable photonic systems featuring minimal power consumption are crucial for integrated optical devices in real-world technology. Current active devices available in foundri…
Reconfigurable all-dielectric metalens with diffraction limited performance
Mikhail Y. Shalaginov, Sensong An, Yifei Zhang +15
Active metasurfaces, whose optical properties can be modulated post-fabrication, have emerged as an intensively explored field in recent years. The efforts to date, however, still…
Extreme Broadband Transparent Optical Phase Change Materials for High-Performance Nonvolatile Photonics
Yifei Zhang, Jeffrey B. Chou, Junying Li +18
Optical phase change materials (O-PCMs), a unique group of materials featuring drastic optical property contrast upon solid-state phase transition, have found widespread adoption i…
Movable thin films with embedded high-index microspheres for super-resolution microscopy
Kenneth W. Allen, Navid Farahi, Yangcheng Li +5
Microsphere-assisted imaging emerged as a surprisingly simple way of achieving optical super-resolution imaging. In this work, we use movable PDMS thin films with embedded high-ind…
