“…O ptical resonances of metallic nanostructures have shown extraordinary capabilities in manipulating visible light in subdiffraction-limited volumes [1][2][3][4][5][6] . This feature enables high-density information encoding using nanostructures that resonate at different wavelengths, as seen in colour prints with resolutions at the diffraction limit of light 7,8 .…”

Metal nanostructures can be designed to scatter different colours depending on the polarization of the incident light. Such spectral control is attractive for applications such as high-density optical storage, but challenges remain in creating microprints with a single-layer architecture that simultaneously enables full-spectral and polarization control of the scattered light. Here we demonstrate independently tunable biaxial colour pixels composed of isolated nanoellipses or nanosquare dimers that can exhibit a full range of colours in reflection mode with linear polarization dependence. Effective polarization-sensitive full-colour prints are realized. With this, we encoded two colour images within the same area and further use this to achieve depth perception by realizing three-dimensional stereoscopic colour microprint. Coupled with the low cost and durability of aluminium as the functional material in our pixel design, such polarization-sensitive encoding can realize a wide spectrum of applications in colour displays, data storage and anti-counterfeiting technologies.

Dual-channel spontaneous emission of quantum dots in magnetic metamaterials

et al. 2013

Metamaterials, artificial electromagnetic media realized by subwavelength nano-structuring, have become a paradigm for engineering electromagnetic space, allowing for independent control of both electric and magnetic responses of the material. Whereas most metamaterials studied so far are limited to passive structures, the need for active metamaterials is rapidly growing. However, the fundamental question on how the energy of emitters is distributed between both (electric and magnetic) interaction channels of the metamaterial still remains open. Here we study simultaneous spontaneous emission of quantum dots into both of these channels and define the control parameters for tailoring the quantum-dot coupling to metamaterials. By superimposing two orthogonal modes of equal strength at the wavelength of quantum-dot photoluminescence, we demonstrate a sharp difference in their interaction with the magnetic and electric metamaterial modes. Our observations reveal the importance of mode engineering for spontaneous emission control in metamaterials, paving a way towards loss-compensated metamaterials and metamaterial nanolasers.

As one of the recent advances of optics and photonics, plasmonics has enabled unprecedented optical designs. Having a vectorial configuration of surface plasmon field, metallic nanostructures offer efficient solutions in polarization control with a very limited sample thickness. Many compact polarization devices have been realized using such metallic nanostructures. However, in most of these devices, the functions were usually simple and limited to a few polarization states. Here, we demonstrated a plasmonic polarization generator that can reconfigure an input polarization to all types of polarization states simultaneously. The plasmonic polarization generator is based on the interference of the in-plane (longitudinal) field of the surface plasmons that gives rise to versatile near-field polarization states on a metal surface, which have seldom been considered in previous studies. With a well-designed nanohole array, the in-plane field of SPPs with proper polarization states and phases can be selectively scattered out to the desired light beams. A manifestation of eight focusing beams with well-routed polarizations was experimentally demonstrated. Our design offers a new route to achieve the full control of optical polarizations and possibly advance the development in photonic information processing. Keywords: near-field interference; phase modulation; plasmonics; polarization generator INTRODUCTIONOptical polarization is an important characteristic of light that enables transmission of information for signal processing in optical information technology by utilizing classical or quantum phenomena. Compared with conventional optical elements, plasmonic devices provide a more compact and efficient means to manipulate the polarization of light (e.g., plasmonic polarizers 1-5 , polarization rotators and converters 6-11 , polarization detectors 12 , etc.). Recently, plasmoninduced spin-orbital coupling has generated strong interest in the field of photonics [13][14][15][16][17] , primarily due to the possibility of polarization and phase modulation. In fact, the vectorial structure of the surface plasmon field gives rise to unique properties in the conversion of optical fields between propagating light and bounded surface plasmon polaritons (SPPs), where the polarization information of light can be reloaded by special SPPs in a controllable way [18][19][20][21][22] . However, most of these devices offer only limited functions in polarization control. To address the ever increasing requirements of information processing, a full polarization generator is one of the desired technologies.The limitations of polarization control would obviously be overcome with the development of a polarization converter that can convert all polarization states at the same time. However, developing such an all-states polarizer in a single device is quite a challenge. Here, we demonstrate such a plasmonic polarization generator that can generate, in principle, all types of polarizations and route them selectively to the appropriate beams in...
