Abstract
Non-local phase-change optical metasurfaces are designed for reconfigurable free-space edge detection/bright-field and edge-detection/blurred imaging functionality. Active reconfigurability is achieved via switching the phase-change material between crystalline and amorphous states. Applications include fast pre-processing for image ...
Non-local phase-change optical metasurfaces are designed for reconfigurable free-space edge detection/bright-field and edge-detection/blurred imaging functionality. Active reconfigurability is achieved via switching the phase-change material between crystalline and amorphous states. Applications include fast pre-processing for image analysis, optical microscopy and more.
