Optical Fiber Meta‐Tips Based on Partial‐Phase Control
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Digitized Phase‐Change Material Heterostack for Transmissive Diffractive Optical Neural Network
A phase‐change‐material‐based digitized heterostack is experimentally demonstrated and theoretically analyzed for future energy‐efficient, fast reconfigured, and compact transmissive diffractive optical neural networks. All‐optical and fully reconfigurable transmissive diffractive optical neural network (DONN) architectures emerge as high‐throughput ...

High‐Fidelity Computational Microscopy via Feature‐Domain Phase Retrieval
An innovative phase retrieval framework, termed FD‐PR, is uniquely established in the image's feature domain through the feature‐extracted, physical‐driven regression with interfaces for combining physics and image processing constraints. FD‐PR takes advantage of invariance components of an image against presences of model mismatch and uncertainty ...
