“…Up to now, a number of on-chip photonic functionalities, such as directional coupling of waveguide modes, highly asymmetric optical power flow, and spatially varying polarization, have been realized by LNOIbased metasurfaces or heterogeneous metasurfaces patterned on LNOI. [172][173][174][175][176][177][178][179][180][181][182][183][184][185][186][187][188][189] These well-designed nanostructures are expected to further enrich the functionality of the RE:LNOI on-chip laser sources in the near future.…”

Rare‐earth (RE) ion doped crystalline materials have a wide spectrum of applications in lasers, amplifiers, sensors, as well as classical and quantum information processing. The incorporation of RE ions into integrated photonics holds great promise for enriching the designer's toolbox with a view to addressing key performance features not available in existing photonic integration platforms. RE‐ion‐doped thin‐film LiNbO3 (also called RE‐ion‐doped lithium‐niobate‐on‐insulator, RE:LNOI), which inherits nearly all the material advantages as well as nanophotonic integration from the LNOI technology, meets the urgent demands for chip‐integrated laser sources, optical amplifiers, and quantum memories based on LNOI photonics. In this article, a timely review is provided on the development of RE:LNOI photonics in terms of ion‐doping techniques, chip‐integrated lasers, and amplifiers, as well as low‐temperature optical characterizations for quantum photonics. To conclude, some well‐noted topics that may shape the future directions in lithium–niobate integrated photonics are discussed.

“…Efficient approaches to realize the integration and application of metasurfaces in on-chip and hybrid photonic systems are still highly desirable, which play a key role in the real application of metasurfaces. [188,189] Exploring the capacity of metasurfaces in the implementation of novel optical functionalities will further promote the development of meta-optics. [190] Recent development in active metasurfaces demonstrated that metasurfaces are not only good candidates for the realization of integration and miniaturization of photonic devices, but also powerful platforms to implement intelligent photonic devices.…”

Recent rapid progress in metasurfaces is underpinned by the physics of local and nonlocal resonances and the modes coupling among them, leading to tremendous applications such as optical switching, information transmission, and sensing. In this review paper, an overview of the recent advances in a broad range of dimensional optical field manipulation based on metasurfaces categorized into different classes based on design strategies is provided. This review starts from the near‐field optical resonances of artificial nanostructures and discusses the far‐field optical wave manipulation based on fundamental mechanisms such as mode generation and mode coupling. The recent advances in optical field manipulation based on metasurfaces in different optical dimensions such as phase and polarization are summarized, and newly‐developed dimensions such as the orbital angular momentum and the coherence dimensions resulting from phase modulation are discussed. Then, the recent achievements of multiplexing and multifunctional metasurfaces empowered by multidimensional optical field manipulation for optical information transmission and integrated applications are reviewed. Finally, the paper concludes with a few perspectives on emerging trends, possible directions, and existing challenges in this fast‐developing field.

“…structure and wavelength-independent phase modulation mechanism, geometric phase metasurfaces have been widely used in recent years. [87][88][89][90][91] However, due to its design for circularly polarized light, additional polarizing and analyzing optical elements are required for highquality light control, which inevitably reduces the light energy efficiency.…”

Metamaterials are artificial structures with the ability to efficiently control light‐field, attracting intensive attention in the past few decades. People have studied the working principles, design strategies, and fabrication methods of metamaterials, making this field cross and combine with many disciplines, including physics, material science, electronics, and chemistry. In recent years, with the rapid development of high‐efficiency and multifunctional metasurfaces, which are a two‐dimensional version of metamaterials, great efforts have been made to push this material to practical applications. In particular, the introduction of artificial intelligent (AI) algorithms enables metamaterials‐based photonic devices that exhibit excellent performances and intelligent functionalities. In this review, we first introduce the basic concepts, working principles, design methods, and applications of metamaterials, and then focus on the rapidly developing metamaterials research combined with AI algorithms. Finally, we conclude this review with personal perspectives on the current problems and future directions of metamaterials research and developments.
