“…Metasurfaces, the two-dimensional analogs of metamaterials composed of ultrathin arrays of planar nanostructures that provide unprecedented control over the transmitted and reflected optical fields, have attracted increasing attention due to their great potentials for ultra-thin, high-performance, and cost-effective optical devices. [2][3][4] By tailoring the optical responses of properly designed and arranged resonant subwavelength elements, the phase, amplitude, and polarization of optical fields can be controlled at will, thereby resulting in numerous applications and compact devices, including beam deflectors, [5][6][7][8][9][10] flat lenses, [11][12][13][14][15][16][17] holograms, [18][19][20][21][22] surface wave couplers, [23][24][25][26][27] and polarimeters. [28][29][30][31] Especially, highlyefficient wave plates have been successfully demonstrated by using gap-surface plasmon (GSP) metasurfaces, which function as effective wave retarders to manipulate the polarization state of light in the reflection mode at the nanoscale.…”

The ability to control and manipulate the polarization state of light is of crucial importance in many modern optical applications ranging from quantum technologies to biomedical sciences. Here we design, fabricate, and experimentally demonstrate an ultrathin quarter-wave plate (QWP) with a gap-surface plasmon metasurface, allowing for broadband and efficient conversion between circular and linear polarizations with ~85% average reflectance across a 200-nm-wide bandwidth in the near-infrared range (750-950 nm). Based on the QWP design, we further derive a general method to generate vector vortex beams (VVBs) that possess spatially-varied distributions of the polarization vector and carry specified orbital angular momentums (OAMs) by using space-variant QWP unit cells. The fabricated metasurface exhibits highly-efficient VVB generation over a wavelength range from 750 to 950 nm, with the average efficiencies of ~72% and ~68% for the right circularlypolarized (RCP) and left circularly-polarized (LCP) incident light, respectively. The developed approach allows one to realize compact, cost-effective and high-performance polarization converters, paving the way for ultimate miniaturization of optical devices with arbitrary control of light fields.

Both amorphous and crystalline silicon are ubiquitous materials for electronics, photonics, and microelectromechanical systems. On-demand control of Si crystallinity is crucial for device manufacturing and to overcome the limitations of current phase-change materials (PCM) in active photonics. Fast reversible phase transformation in silicon, however, has never been accomplished due to the notorious challenge of amorphization. It is demonstrated that nanostructured Si can function as a PCM, since it can be reversibly crystallized and amorphized under nanosecond laser irradiation with different pulse energies. Reflection probing on a single nanodisk's phase transformations confirms the distinct mechanisms for crystallization and amorphization. The experimental results show that the relaxation time of undercooled silicon at 950 K is 10 ns. The phase change provides a 20% nonvolatile reflectivity modulation within 100 ns and can be repeated over 400 times. It is shown that such transformations are free of deformation upon solidification. Based on the switchable photonic properties in the visible spectrum, proof-of-concept experiments of dielectric color displays and dynamic wavefront control are shown. Therefore, nanostructured silicon is proposed as a chemically stable, deformation free, and complementary metal-oxide-semiconductor compatible (CMOS) PCM for active photonics at visible wavelengths.

“…Distinct from conventional EM devices that modulate the EM wave via gradually accumulated phase changes during wave propagation, gradient metasurfaces can engineer the amplitude, phase, and polarization locally by directly modifying the boundary conditions. As such, gradient metasurfaces can mimic bulk EM devices, and numerous flat functional components have been accordingly demonstrated, such as beam steerers [10], [23]- [27], metalenses [28]- [36], holograms [37]- [43], waveplates [44]- [48], and polarimeters [49]- [55].…”

Efficient and unidirectional excitation of surface plasmon polaritons (SPPs) and their low-frequency counterparts (i.e., spoof SPPs) is highly desired in the research area of photonics and plasmonics, while being at the same time rather challenging. Recent progress in gradient metasurfaces, ultrathin and planar materials composed of sub-wavelength unit cells, has opened up new possibilities for efficiently coupling of free-space propagating waves to surface waves. In this paper, we will discuss the recent achievements in gradient metasurface-based unidirectional SPP couplers (i.e., metacouplers). Starting with explaining the basic concept of generalized Snell's law, we then introduce some typical examples of unidirectional SPP metacouplers, followed by an overview of polarization-controlled tunable SPP metacouplers. We also describe metacouplers that also feature other functionalities, beyond the unidirectional SPP excitation. The review is concluded with a short summary and perspective for future developments.
