Summary: This paper reports the design, fabrication, and experimental demonstration of conformable holographic metasurfaces. It is demonstrated that the holographic image produced changes when the metasurface is applied to targets with different shapes. The demonstration is based on a reflective-type metasurface with perpendicular reflected polarization to the incident light. Additionally, the parameters of the metasurface and their influence on the image quality and ability to produce independent images are critically discussed.

Summary: The combination of biological mimicry and metasurface designs has led to the development of holographic mimicry devices. A general mathematical method called phase matrix transformation is used to achieve the holographic mimicry process. Dynamic metasurface holograms have been designed to display different images in varying environments, and holographic mimicry operating at dual wavelengths has been experimentally demonstrated. The fully independent phase modulation realized by phase matrix transformation enhances the working efficiency of the devices, potentially opening up new research avenues for applications such as optical information encryption, VR/AR, and military camouflage systems.

Summary: Simultaneous realization of printing and holographic images is an emerging technology that improves optical storage and anti-counterfeiting. This paper proposes a four-channel metasurface that can support four independent circular polarization information channels. The metasurface allows for flexible design of operation frequencies and achieves polarization multiplexing and frequency multiplexing. Experimental results show that printing and holographic images with different handedness can be stored at one or two different frequencies. This metasurface provides a new avenue for the design of photonic devices with multiple functionalities, with potential applications in anti-counterfeiting, data storage, and image display.

Summary: A revolutionary technology called Stacked Intelligent Metasurfaces (SIM) enables advanced signal processing in the electromagnetic (EM) wave regime. SIM, which consists of multiple stacked metasurface layers, outperforms single-layer metasurfaces like reconfigurable intelligent surfaces (RIS) and metasurface lenses. In this study, we utilize SIM to implement holographic multiple-input multiple-output (HMIMO) communications without excessive radio-frequency (RF) chains. We propose an HMIMO communication system based on a pair of SIM at the transmitter (TX) and receiver (RX), respectively, and optimize the phase shifts of all metasurface layers to minimize the error between the actual channel matrix and the target diagonal matrix.

Summary: A metasurface with chiral structures is demonstrated, providing multifunctionality with multiple wavefront information depending on the polarization of incident light. It integrates a liquid crystal for fast switching and dynamic optical response in transmission mode at broadband visible wavelengths. Chiral z-shaped meta-atoms are used to avoid phase distortion and encode holographic information into the metasurface. The experimental validation shows the reproduction of spin-dependent-specific information by changing the polarization of incident light. This research paves the way for highly efficient multifunctional metadevices for next-generation holographic displays in healthcare, media, smart security, and data encryption.

Summary: Dispersion is a common phenomenon in optical systems and is often undesirable, especially in nonlinear-optical experiments requiring ultrashort laser pulses. A compact pulse-shaping device using plasmonic metasurfaces is introduced to achieve full dispersion control by applying a designed spectral phase delay. Additionally, the device can reshape incident laser pulses into more complex forms, such as a double pulse, through specific phase encodings. The device's performance is verified using an SHG-FROG measurement setup and a retrieval algorithm to extract the dispersion applied to the incident laser pulse.

Summary: Achromatic metalenses offer potential for miniaturizing optical systems, but the limited group delay range of fabricable meta-atoms creates a trade-off relationship between working bandwidth, numerical aperture (NA), and aperture. This study presents an efficient end-to-end inverse design framework for multiwavelength achromatic metalenses, taking into account the narrow bandwidth of light sources typically used in optical systems. A proof of concept achromatic metalens with NA 0.3 and diameter 115 μm is designed and demonstrated, showing a maximum focal length shift of 5.2778%. This strategy allows for complex functionalities to be integrated into a single metasurface, driving the design of efficient and emerging devices.

Summary: This paper proposes a dynamic THz metasurface combined with the phase-change material VO2 that can be thermally controlled for optical encryption. By arranging antennas in advance and utilizing the electromagnetically induced transparency effect, a secret image can be encoded into the metasurface. When the temperature exceeds the phase-change temperature, the encrypted hologram can be reconstructed. With the distinct characteristics of VO2, the phase-change temperature required for decryption is not very high, and the entire process is reversible. It is expected that such metasurfaces can be practically applied to the next generation of optical encryption or optical anticounterfeiting in the future with updated processing technology.
