Orthogonal three-dimensional manipulation of a chiro-photonic hybrid-architecture enabling high-order information encryption

Abstract

Multidimensional microstructure manipulation for tailored optical and physical properties remains a fundamental challenge in photonic materials engineering, which is primarily hindered by multi-field response correlations in self-assembling systems and the inherent static properties of fabricated microstructures. Here we present a groundbreaking approach that enables the orthogonal three-dimensional manipulation of a chiro-photonic hybrid-architecture via self-assembly of soft helices on surface relief nanostructures. This advanced hybrid-architecture allows for independent control of three critical structural parameters, including relief period, relief vector orientation and helical pitch. The period governs spectral information within individual channels, while the vector orientation switching facilitates channel integration and photoprogramming of the helical pitch further introduces dynamic spectral variations, collectively establishing a deterministic structure-information mapping paradigm. A straightforward encoding prototype has been implemented by using a three-channel multiplexed framework based on optical wavevector and spectral information, substantially achieving a tenfold enhancement in information capacity compared with conventional microstructures. Our work extends the capabilities of current technologies in responsive soft materials and opens new avenues for prospective application in dynamic multidimensional optical information modulation and integration systems.
