“…To design a metasurface holographic device (phase only or complex), discrete phase shifts are the crucial information that can be tailored by engineering the spatial dimensions and/or orientation of the meta-elements depending upon the input/ output polarization of the light. Several polarization-dependent and independent metasurface holograms have been reported for linearly polarized light [11,14,[43][44][45][46][47] . For CP light, most meta-holograms involving the spin of light display the holographic image on the cross polarization, making them sensitive to handedness of the incident light [48][49][50][51][52] .…”

“…Polarization of the incident light plays a key role in light-matter interaction for wavefront manipulation; however, geometry of meta-elements makes the metasurfaces sensitive to the incident polarization of the light. There have been several efforts to realize singlelayered polarization-insensitive metasurfaces for wavefront engineering functionalities, e.g., meta-holograms, metalenses, and beam steering for linear and circular polarization [11][12][13][14][15][16] . For circularly polarized (CP) wavefront manipulation, these metasurfaces either use propagation phase or compound geometric and propagation phase to obtain the desired phase profiles on CP orthogonal polarization.…”

Metasurfaces, two-dimensional (2D) or quasi-2D arrays of dielectric or metallic meta-atoms, offer a compact and novel platform to manipulate the amplitude, phase, and polarization of incoming wavefronts in a desired manner by engineering the geometry of meta-atoms. In polarization control, spin-insensitive metasurfaces have attracted significant attention due to the robustness of circular polarization against the beam misalignment and multi-path effects. Till now, several efforts have been made to realize polarization-insensitive metasurfaces for circularly polarized (CP) wavefront manipulation; however, these metasurfaces only consider the cross-polarization channels and keep the co-polarization channels abandoned. Such metasurfaces cannot be considered truly spin-insensitive, as one has to carefully choose the analyzer at output. Here, by combining the polarization-insensitive geometric phase and engineered propagation phase, we propose a spin-insensitive design principle based on metasurfaces that can perform identical functionality (on co-and crosspolarization channels) irrespective of the handedness of incident/transmitted light. As a proof of concept, we design and numerically realize two types of spin-insensitive wavefront engineering devices: (1) spin-insensitive meta-hologram and (2) spin-insensitive beam deflector with power splitting functionality. The proposed work is expected to open up new avenues for developing spin-independent metasurfaces-based devices.

“…The conversion efficiency of such a design technique is theoretically limited to 50% . In other studies, amplitude manipulation-based polarization-insensitive metasurfaces are reported. , Such metasurfaces depict the holographic output in the near field of the metasurface, making them unsuitable for such biomedical packaging security applications. Therefore, there is a strong need to develop a new phase-manipulation-based polarization-insensitive metadevice designing technique that can break all of the aforementioned limitations.…”

Secure packaging and transportation of light-sensitive chemical and biomedical test tubes are crucial for environmental protection and public health. Benefiting from the compact form factor and high efficiency of optical metasurfaces, we propose a broad-band polarization-insensitive flexible metasurface for the security of sensitive packages in the transport industry. We employ both the propagation and the geometric phase of novel TiO2 resin-based anisotropic nanoresonators to demonstrate a flexible and broad-band polarization-insensitive metasurface in the visible domain. The ultraviolet nanoimprint lithographic technique (UV-NIL) is used to fabricate high-index TiO2 nanoparticle-embedded-resin (nano-PER) structures that are patterned on a flexible substrate. This novel approach provides swift single-step fabrication without secondary fabrication steps such as deposition and etching. Moreover, replicating and transforming patterns over flexible substrates make the proposed technique highly suitable for large-throughput commercial manufacturing. As the proposed metahologram manifests high transmission efficiency in the visible domain, such flexible metaholographic platforms could find several exciting applications in bendable/curved displays, wearable devices, and holographic labeling for interactive displays.

“…Recently, owing to the unprecedented ability to modulate electromagnetic waves, metasurfaces can precisely manipulate the phase, amplitude, and polarization of the incident light with subwavelength dimensions [ 5 , 6 , 7 , 8 , 9 ], which pave a new path to encode and display multi-channel images [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Among them, nanoprinting and holographic images are emerging research fields.…”

Metasurfaces, employed to simultaneously generate nanoprinting and holographic images, have been extensively explored recently. Among them, multi-wavelength multiplexing in a single metasurface is often accompanied by dispersion and crosstalk, which hinder the display of multicolor patterns. Here, we propose an efficient phase method to decouple the wavelength and realize a three-channel display operating at different wavelengths. Holographic images appear in the far field with the illumination of two different circularly polarized lights while a nanoprinting image is reconstructed by inserting an orthogonal optical path with the illumination of linear polarization light. The proposed metasurface is only composed of four types of unit cells, which significantly decreases the complexity of fabrication and improves the information capacity. Benefiting from its different decoding strategies and capability of multi-wavelength control, this approach may develop broad applications in information encryption, security, and color display.
