van der Waals magnetic materials open up exciting possibilities to investigate fundamental spin properties in low-dimensional systems and to build compact functional spintronic structures. This review focuses on the recent progress in two-dimensional(2D) magnets that explore beyond the homogenous magnetically-ordered state, including magnons (spin waves), magnetic skyrmions, and complex magnetic domains. Properties of these spin and topology excitations in 2D magnets provide insights into spin-orbit interactions and other forms of coupling between electrons, phonons, and spin-dependent excitations. Such spin-based quasiparticles can also serve as information carriers for next-generation high-speed computing elements. We will first lay out the general theoretical basis of dynamical responses in magnetic systems, followed by detailed descriptions of experimental progress in magnons and spin textures (including magnetic domains and skyrmions). Discussion on the experimental techniques and future perspectives are also included.

Concentrating photovoltaics (CPV) use inexpensive optics to concentrate sunlight onto high efficiency solar cells. Over the past decade, the field of CPV has evolved from large systems aimed at grid-scale power generation toward microconcentrating photovoltaics (µCPV) that employ miniaturized cells and compact optics to address new, performance-driven applications such as agrivoltaics and space power. This review summarizes the development, present status, and future prospects of this emerging subfield. We discuss the main components that make up a typical µCPV system and highlight some of the key results achieved to date before concluding with a look forward at the milestones that will be needed to transition µCPV out of the lab and into the real world.

In optoelectronics, achieving electrical reconfigurability is crucial as it enables the encoding, decoding, manipulating, and processing of information carried by light. In recent years, two-dimensional van der Waals (2-D vdW) materials have emerged as promising platforms for realizing reconfigurable optoelectronic devices. Compared to materials with bulk crystalline lattice, 2-D vdW materials offer superior electrical reconfigurability due to high surface-to-volume ratio, quantum confinement, reduced dielectric screening effect, and strong dipole resonances. Additionally, their unique band structures and associated topology and quantum geometry provide novel tuning capabilities. This review article seeks to establish a connection between the fundamental physics underlying reconfigurable optoelectronics in 2-D materials and their burgeoning applications in intelligent optoelectronics. We first survey various electrically reconfigurable properties of 2-D vdW materials and the underlying tuning mechanisms. Then we highlight the emerging applications of such devices, including dynamic intensity, phase and polarization control, and intelligent sensing. Finally, we discuss the opportunities for future advancements in this field.

This paper reviews recent advances in millimeter-wave (mmWave) piezoelectric acoustic resonators and filters, based on thin-film lithium niobate (LN) platforms. Recent utilization of transferred thin-film LN (TFLN) on various substrates has enabled high-performance microelectromechanical systems (MEMS) devices. For mmWave applications, TFLN supports an assortment of acoustic modes with large electromechanical coupling (k2), high quality factors (Q), and great frequency scalability. These features have led to significant recent performance enhancements in low-loss and wideband resonators and filters using TFLN. More specifically, acoustic resonators between 18 and 100 GHz have been demonstrated with low loss, compact form factors, and strong piezoelectric coupling. Acoustic filters have also been shown at mmWave frequency ranges, beyond the conventional sub-6 GHz operating range, toward addressing the stringent demands of future wireless communication systems. The review starts by analyzing the background and challenges of frequency scaling incumbent acoustic technologies, then introduces the unique potentials of TFLN platforms for mmWave resonator applications, highlighting fabrication techniques and novel device architecture. Beyond this, periodically poled piezoelectric film (P3F) LN is highlighted. The multi-layer structure with alternating orientations in adjacent layers enables high figure of merit (FoM = k2∙Q) acoustic devices at mmWave, efficiently coupling electrical and mechanical energy while minimizing damping in thicker film stacks. Finally, mmWave acoustic filter implementations have been reviewed and followed by outlooks for future work in mmWave acoustics.

<div><div>The efficiencies of light emission and absorption are two key factors for the effective operations of many optoelectronic devices. Those efficiencies can be improved through the efforts of upgrading material quality and optimizing device design. When such an improvement reaches a limit in considering the technological difficulty and/or fabrication cost, other means based on nano-photonics techniques deserve consideration. In particular, due to the development of the nano-fabrication technology and the trend of shrinking device dimension, those techniques based on near-field interactions are attractive. Among them, surface plasmon (SP) coupling is a powerful method for enhancing the emission and absorption efficiencies. Also, when color conversion is needed, the Förster resonance energy transfer (FRET) is an effective approach for transferring energy from a donor into an acceptor within a short range. In this paper, the basic principles, the fundamental behaviors, and the applications to the enhancements of light emission and color conversion of SP coupling are reviewed. The SP coupling here is referred to as that not strong enough to produce the phenomenon of Rabi splitting. For effective color conversion, the combined effects of FRET and SP coupling are also discussed. Meanwhile, the nanoscale-cavity effect is introduced to combine with FRET and SP coupling for further enhancing the emission and color conversion efficiencies. The review starts with the behaviors of the SP resonances of metal nanostructures, particularly those of metal nanoparticles (NPs), including deposited surface metal NP and chemically synthesized metal NP, due to their easy fabrication, low cost, and strong localized SP resonance. Among the metals with the negative real parts of dielectric constants for inducing SP resonances in the ultraviolet through near-infrared spectral range, Ag is the major concern in this review because of its high SP resonance strength and low dissipation. SP coupling can be understood as a process of the energy transfer from a light emitter into an SP resonance mode for creating an alternative emission channel, i.e., the coherent SP radiation. A model and a derivative simulation algorithm, which take the Purcell effect into account, are reviewed for interpreting experimental observations. SP coupling can be used for improving the performances of a light-emitting diode (LED), including the enhancements of internal quantum efficiency and electroluminescence intensity, the reduction of the efficiency droop effect, the increase of modulation bandwidth, and the generation of partially polarized light in an LED. SP coupling can also be used for increasing the efficiency of a color conversion process. In such a process, the energy donor, acceptor, and metal nanostructure can be coupled together through an SP resonance mode around the donor emission or acceptor absorption wavelength for forming a three-body coupling system.

Nanophotonic devices have marked a significant advance in light control at the subwavelength level, achieving high efficiency and multifunctionality. However, the precision and functionality of these devices come with the complexity of identifying suitable meta-atom structures for specific requirements. Traditionally, designing metasurface devices has relied on time-consuming trial-and-error methods to match target electromagnetic (EM) responses, navigating an extensive array of possible structures. Recently, deep learning (DL) has emerged as a potent alternative, streamlining the forward modeling and inverse design process of nanophotonic devices. This review highlights recent strides in deep-learning-based photonic modeling and design, focusing on the fundamentals of various algorithms and their specific applications, and discusses the emerging research opportunities and challenges in this field.

Traditional nonlinear optics emphasizes processes driven by the electric field of light at moderately high intensities while generally ignoring dynamic magnetic effects. High frequency magnetism is generally associated with metamaterials or bulk magneto-electric solids. However, magneto-electric interactions can achieve magnetic response at the molecular level in essentially all dielectric materials. Classical and quantum models of nonlinear interactions driven by the combined forces of optical electric and magnetic fields are reviewed in this paper. Experimental conditions are also identified under which electric and magnetic field-driven interactions induce enhanced magnetic dipole response as well as a longitudinal Hall effect. Several mechanisms that account for dynamic enhancement of magnetic response are identified, including a torque-driven exchange of orbital angular momentum for rotational angular momentum. Experiments on this topic are summarized, and connections are established between electric and magneto-electric susceptibilities. The review concludes by anticipating novel photonic technology reliant on dynamic magneto-electric effects.

Nonpolar atoms or molecules with low particle mass and weak inter-particle interactions can form quantum liquids and solids (QLS) at low temperatures. Excess electrons naturally bind to the surfaces of QLS in a vacuum, exhibiting unique quantum electronic behaviors in two and lower dimensions. This article reviews the historical development and recent progress in this field. Key topics include collective and individual electron transport on liquid helium, solid neon, and solid hydrogen; theoretical proposals and experimental efforts towards single-electron qubits on superfluid helium; experimental realization of single-electron charge qubits on solid neon and related theoretical investigation. Finally, we discuss and envision future exploration of quantum electronics in heterogeneous QLS systems.

The quantum internet is on the cusp of a revolution. While it shares the same purpose as the classical internet — connecting devices and transmitting information, the underlying principle of quantum physics makes the quantum internet a disruptive technology that will enable services unmatched by the classical internet. The quantum internet design has moved beyond theory. The past decade has seen a surge of efforts among researchers worldwide in building quantum network testbeds, a crucial stepping stone toward the quantum internet. In this review paper, we will summarize recent progress on quantum network testbeds, highlighting their major demonstrations and achievements. This progress report is the first of its kind in the literature, offering a holistic view of past regional efforts and prompting the community to assess our current position. Moreover, this paper will discuss open challenges and envision a collaborative pathway forward for the development of the quantum internet.
