Dielectric metasurfaces built up with nanostructures of high refractive index represent a powerful platform for highly efficient flat optical devices due to their easy-tuning electromagnetic scattering properties and relatively transmission efficiencies.

In the context of current sharing economy, application shared energy storage (SES) among local integrated systems (LIESs) is underexplored. There an urgent need for developing appropriate modeling and solution methods so as to facilitate SES LIESs. To this end, paper proposes a cooperative-game-based day-ahead scheduling model LIESs with SES. The proposed can be transformed into sequential two-step optimization problem alleviating computational complexity. More specifically, subproblem...
Quantum networks provide the framework for quantum communication, clock synchronization, distributed computing, and sensing. Implementing large-scale practical relies on development of scalable architecture integrated hardware that can coherently interconnect many remote nodes by sharing multidimensional entanglement through complex-medium channels. We demonstrate a multichip network based mass-manufacturable integrated-nanophotonic node chips fabricated silicon wafer means complementary...
We have measured the spin-dependent nanometer-sized displacements of spin Hall effect reflected light from a planar air-glass interface. In case vertical polarization, displacement is found to increase with incident angle and subsequently decrease after approximately 48 deg, while in horizontal it changes rapidly near Brewster angle. For fixed 30 decreases zero as polarization approaches 39 deg 0 (the polarization) then increases opposite direction until 90 polarization).
By moving silica glass in a preprogrammed structure, we directly produced three-dimensional holes with femtosecond laser pulses single step. When distilled water was introduced into hole drilled from the rear surface of glass, effects blocking and redeposition ablated material were greatly reduced aspect ratio depth increased. Straight 4‐μm diameter more than 200 μm deep. Three-dimensional channels can be micromachined inside transparent materials by use this method, as have demonstrated...
Fabricated by femtosecond laser pulses at wavelength λ of 780nm, the feature size two-photon polymerization using SCR500 was reduced to λ∕50. Lines with sub-25-nm width were produced controlling incident power and focus scan speed up 700μm∕s. Based on repolymerization between two structures close each other, further ∼15nm, which demonstrated potential for three-dimensional nanofabrication high spatial resolution.
We propose a kind of plasmonic whispering-gallery mode highly localized on the exterior surface metal-coated microresonator. This (EX) possesses high quality factors at room temperature, and can be efficiently excited by tapered fiber. The EX couple to an interior (IN) this coupling produces strong anticrossing behavior, which not only allows conversion IN modes, but also forms long-lived antisymmetric mode. As potential application, could used for biosensor with sensitivity up 500 nm per...
We propose a hybrid photonic-plasmonic resonant structure which consists of metal nanoparticle (MNP) and whispering gallery mode (WGM) microcavity. It is found that the enables strong interaction between light matter, single-atom cooperativity enhanced by more than two orders magnitude compared to in bare WGM This remarkable improvement originates from aspects: (1) MNP offers highly local field vicinity an emitter, (2), surprisingly, high-\textit{Q} property WGMs can be maintained presence...
A high-sensitivity thermal sensing is demonstrated by coating a layer of polydimethylsiloxane (PDMS) on the surface silica toroidal microresonator silicon wafer. Possessing high-Q whispering gallery modes (WGMs), PDMS-coated highly sensitive to temperature change in surroundings. We find that, when PDMS becomes thicker, WGM experiences transition from redshift blueshift with increasing due negative thermal-optic coefficient PDMS. The measured sensitivity (0.151 nm/K) one order magnitude...
The Active Disturbance Rejection Control (ADRC) prefers the cascaded integral system for a convenient design or better control effect and takes it as typical form. However, state variables of practical do not necessarily have relationship. Therefore, this paper proposes an algebraic substitution method its structure, which can convert noncascaded PID into adjusting parameters ADRC controller are also demonstrated. Meanwhile, numerical example oscillation flexible arm demonstrated to show...
We experimentally observe Fano resonance in a single silica toroidal microresonator, which two whispering-gallery modes (WGMs) are excited simultaneously through fiber taper. By adjusting the fiber-cavity coupling strength and polarization of incident light, Fano-like line shape can be engineered further convert to electromagnetically induced transparency (EIT) like shape. Our theoretical analysis reveals that both EIT resonances originate from an indirect-coupling originally orthogonal...

By doping erbium, the unidirectional-emission lasing observed 1550 nm band with threshold as low 2 μW. Confinement manipulation photons using have triggered intense research interest more than a...
We experimentally studied the transmission spectrum of a coupled resonator structure in which low-Q microdisk and high-Q microtoroid indirectly interact with each other mediated by fiber taper. Asymmetric Fano resonances were observed could be controlled to change periodically adjusting distance between two microresonators. It is revealed that resonance originates from coupling modes belonging The period around 8 μm, shows good agreement theoretical prediction beat multiple propagating
We reveal that there exists an indirect interaction between two single-mode microcavities which have no direct coupling. This is mediated by coupling the to a common waveguide, and it plays key role in obtaining asymmetric Fano line shape of transport spectrum coupled cavity system. Finally, we show this sharp can contribute highly sensitive sensing, immune most environmental variations.

Here we experimentally demonstrate that during reflection or refraction at a single optical planar interface, the computing of spatial differentiation can be realized by analyzing specific orthogonal polarization states light. We show is intrinsically due to spin Hall effect light and generally accompanies any regardless material composition incident angles. The proposed spin-optical method takes advantages simple...
Vivid images can be created with metasurface color holograms by configuring their subwavelength planar structures. However, it is a challenge to arbitrarily tune the colors of after metasurfaces have been fabricated. The common method balancing incident intensities individual wavelengths directly or indirectly does not change relative brightness/color different parts image. Here, we use spin manipulation and wavelength multiplexing only entire holographic image but also defined it. This...
Artificial metasurfaces are capable of completely manipulating the phase, amplitude, and polarization light with high spatial resolutions. The emerging design based on high-index low-loss dielectrics has led to realization novel transmissions, but these devices usually operate at limited bandwidth, sensitive incident polarization.
