Abstract :

Chirality is a universal geometric property in both micro- and macroworlds. Recently, optical chiral effects have drawn increased attention due to their great potential in fundamental studies and practical applications. Significantly, the optical chiral response of artificial structures can be enhanced by orders of magnitude compared to that of their naturally occurring counterparts. These man-made structures generally exhibit two types of optical chirality: extrinsic chirality and intrinsic chirality. The former relies on external illumination conditions, while the latter arises from the geometric characteristics of 3D objects. Herein, this review mainly focuses on the intrinsic chirality of artificial structures and discusses the existing realizations based on their design principles. In particular, an overview is given of the recent demonstrations of nonlinear optical effects in chiral structures and active chiral structures. Lastly, some promising prospects for future studies in the field are outlined. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Modulation of the High-Order Laguerre-Gaussian Beam in Dressing Four-Wave Mixing EI SCIE Scopus

Abstract&Keyword Cite

Abstract :

We report an experiment about the transformation of radical and azimuthal information of high-order Laguerre-Gaussian beam from the probe beam to dressing four-wave mixing beam. During this process, dressing Kerr nonlinear dispersion causes a spatial splitting on output Laguerre-Gaussian beam. We found that the number of split spots can be controlled by frequency detuning and power of the dressing field. The potential application of such modulated spatial splitting phenomenon on optical switching of the multi-channel router in atomic ensembles is discussed.

Wavenumber-Splitting Metasurfaces Achieve Multichannel Diffusive Invisibility EI SCIE Scopus

Abstract&Keyword Cite

Abstract :

The emerging invisibility schemes mainly adopt transformation optics, scattering cancellation, light diffusion, and metasurface-based phase restoration techniques. However, those aforementioned invisibility achievements natively depend on the predefined curvature, polarization, frequency, and/or angle of the incident wave. Here, an invisibility strategy of using an ultrathin parabolic-phase metasurface and its applications to achieve diffusive invisibility for dual-polarization channels and multifrequency channels is reported. Such strategy can intrinsically split the wavenumber of the scattering wave and therein is termed as wavenumber-splitting metasurface. For verification, two proof-of-concept examples are experimentally characterized. The first prototype manifests dual-polarized near-isotropic diffusive scattering immune from wide-angle incidences. The second demonstration exhibits bifunctionality of combined diffusive invisibility and vortex scattering in dual-polarization channels. In both cases, theoretical, numerical and experimental results agree well, illustrating a well-separated triple-band versatile scattering behavior. This approach addresses the fundamental issue of real invisibility under bistatic detection without complex optimization, thanks to the physical essence of numerous splitting wave vectors. Such strategy opens an upstream way to realize invisibility as well as holding the potentials for downstream applications such as stealth and camouflaging devices.

Gold nanoparticle mediated graphene plasmon for broadband enhanced infrared spectroscopy EI SCIE Scopus

Abstract :

Graphene plasmonics, with dynamic tunable resonance wavelength, has been successfully used in broadband plasmon-enhanced infrared spectroscopy. However, the requirement for external voltage loading makes the practical application sophisticated. In this work, the hybrid structure of graphene nanodot array (GNA) and gold nanoparticles (AuNPs) has been proposed as a passive platform for broadband infrared absorption enhancement. Numerical simulations show that the plasmon resonance peak of GNA becomes stiffer and broader when introducing AuNPs, and this is also proved by experimental results that the vibrational modes of polyethylene oxide molecule in a broad spectral range can be simultaneously enhanced. The metal-graphene hybrid plasmonic system has been proved to be a promising candidate for infrared sensing, which is significant for safety and healthy applications.

Dielectric Meta-Holograms Enabled with Dual Magnetic Resonances in Visible Light EI SCIE PubMed Scopus

Abstract :

Efficient transmission-type meta-holograms have been demonstrated using high-index dielectric nanostructures based on Huygens principle. It is crucial that the geometry size of building blocks be judiciously optimized individually for spectral overlap of electric and magnetic dipoles. In contrast, reflection-type meta-holograms using the metal/insulator/metal scheme and geometric phase can be readily achieved with high efficiency and small thickness. Here, we demonstrate a general platform for design of dual magnetic resonance based meta-holograms based on the geometric phase using silicon nanostructures that are quarter wavelength thick for visible light. Significantly, the projected holographic image can be unambiguously observed without a receiving screen even under the illumination of natural light. Within the well-developed semiconductor industry, our ultrathin magnetic resonance-based meta-holograms may have promising applications in anticounterfeiting and information security.

Realization of Full Control of a Terahertz Wave Using Flexible Metasurfaces EI SCIE Scopus CSSCI-E

Abstract :

Compared with devices controlling microwave and visible light, there is a lack of functional devices for terahertz (THz) wave control. Moreover, the available THz elements are usually manufactured with bulk materials, in contrast to the trend of miniaturization and compact device requirements. Here, full control of both phase and amplitude is achieved experimentally and numerically at 0.14 THz, one of the atmospheric windows, by demonstrating the functionalities such as polarization conversion, metalenses and the generation of a non-diffraction Airy beam. Significantly, the metal structures are fabricated on a flexible substrate with a total thickness of ≈0.063 l via a standard flexible printed circuit technique. Taking into account the considerable manipulation efficiency and cost-efficient sample fabrication technique, the results show solid advances in the development of metasurfaces as a versatile platform for designing practical functional devices in the THz range. © 2017 WILEY-VCH Verlag GmbH & Co.

Abstract :

Strong confinement and long-range propagation of electromagnetic energy are longed for when designing efficient miniaturized photonic devices. Here, a graphene-coated nanowire with a drop-shaped cross section is proposed for guiding graphene surface plasmon polaritons to demonstrate an extremely long propagation length (1 mm) with ultra-strong mode confinement (10 nm), which results from the distinctive mode field distribution caused by both the top and bottom arcs of the waveguide. The combination of nanoconcentration and long-range propagation makes the waveguide very useful in nanophotonics, bio-photonics, and highly integrated photonic circuits.
