Four‐Channel Vectorial Metasurface Holography with Statistically Matched Patterns for Deceptive Optical Communication

ABSTRACT Metasurface holography has emerged as a powerful platform for high‐capacity optical encoding; however, conventional optical encryption typically hides information in stochastic noise, revealing the message only under specific polarization states. Here, we propose a decep...

Symmetry-cooperative optical-field engineering for ultrabroadband bulk photovoltaic photodetection

The bulk photovoltaic effect (BPVE) enables light-to-electricity conversion without external bias, but its practical reach is constrained by the rapid collapse of photoresponse at low photon energies. Here we show that this limitation can be overcome through cross-scale symmetry...

Multidimensional Sensing in Flexible Violet Phosphorus Photodetectors Driven by the Bulk Photovoltaic Effect

ABSTRACT The bulk photovoltaic effect (BPVE) generates zero bias photocurrents in systems with broken inversion symmetry, offering a junction free pathway for self‐powered optoelectronic devices and conceptually overcoming the Shockley‐Queisser efficiency limit of conventional ju...
