Abstract Numerous structures at the nano and microscale manifest distinctive properties with far-reaching implications across diverse fields, including electronics, electricity, medicine, surface engineering. Established methods such as nanoimprint lithography, photolithography, self-assembly play crucial roles in fabrication of nano- microstructures; however, they exhibit limitations generating high-aspect-ratio when utilizing high-viscosity photocurable resins. In response to this inherent challenge, we propose a highly cost-effective approach facilitating direct replication structures, specifically nanowires, through utilization anodized aluminum substrates.

Integrating metasurfaces on-chip offers a promising strategy for modulating and extracting guided waves, suggesting tremendous applications in compact wearable devices. However, despite the full acquisition of manipulation optical parameters, including phase, amplitude, polarization, functionality remains limited by lack wavelength selectivity. Here, an approach to differentiate components is proposed visible regime division multiplexing (WDM). Through horizontally cascading meta-atoms with structural dimension variation optimization, different propagating along waveguide would be selectively extracted, realizing meta-demultiplexing functionality. More intriguingly, color nanoprinting images or holographic displays can correspondingly enabled. This surpasses conventional free-space meta-devices terms exhibiting improved wavelength-selective allocation eliminating energy waste caused spatial multiplexing. We envision that such paves way next-generation WDM devices photonic integrated circuits miniature meta-displays.
