Abstract

A method for displaying volumetric images, which exploits our binocular vision and does not require eyewear, is discussed. The display can be rendered as a matrix of pivoting micromirrors irradiated by a light beam; each micromirror focuses its pixel beams to the same point of displayed volumetric image. 3D perception of image can be achieved by scanning the point of beams intersection over a virtual surface of displayed image in space.

Molecule-by-molecule nanoresolved picosecond Purcell-enhanced emission at room-temperature in hollow plasmonic nanocone metamaterials

Nanoscale variations in the electromagnetic environment strongly influence quantum emission processes, yet direct quantitative visualization of these effects at the single-emitter level remains challenging. By combining single-molecule super-resolution microscopy with time-correlated single-photon counting (TCSPC), we read the local electromagnetic environment of each molecule from its position and its excited-state lifetime. Using wafer-scale arrays of hollow plasmonic nanocones, we map position-dependent variations in the local density of optical states (LDOS) along the nanocone axis. We observe pronounced LDOS gradients that evidence a shortening of the fluorescence lifetime from nanoseconds to few picoseconds. The measured decay rates along the nanocone axis with maximum value at the top ring, yielding a total spontaneous-emission rate enhancement of more than two orders of magnitude at the single-molecule level, reaching an enhancement of the total spontaneous-emission rate of up to two orders of magnitude at the single-molecule level, in agreement with numerical simulations. These results provide direct experimental access to three-dimensional electromagnetic landscapes and establish a non-perturbative platform for quantitative molecular nanosensing in complex photonic architectures. The approach opens new opportunities for engineered room-temperature photon sources, vectorial field sensing, and scalable integrated nanophotonic technologies.

Optical chirality of membrane metasurfaces with broken in-plane symmetry

We study chiroptical properties of single-layer dielectric membrane metasurfaces with broken in-plane symmetry. Although chiral optics was long tied to structures lacking any mirror symmetry, planar (2D) chiral structures that retain a horizontal mirror plane now attract growing attention for their strong chiral optical effects. We explicitly show and explain how single-layer metasurfaces can achieve strong resonant chiral response. Although the single-layer geometry forbids conventional co-polarized circular dichroism, strong resonant conversion circular dichroism appears to be possible in particular wavelength ranges determined by the spectra of photonic eigenmodes. We explore its origin starting with a $C_4$ rotation-symmetric and in-plane mirror-symmetric membrane metasurface and applying to it various in-plane perturbations. Simultaneous breaking of the in-plane mirror symmetry and lifting the rotation symmetry unlocks resonantly enhanced circular conversion dichroism. We derive selection rules for this effect and trace its origin to eigenmode interference and intercoupling using chiral coupled-mode theory. Material absorption weakens the conversion dichroism produced by modes of opposite up-down parity, but it is essential for that produced by modes of the same parity.

Beam shifts and eigenpolarisations for the reflection of vortex beams from homogeneous magnetic surfaces

Probing surfaces with optical beams is a powerful technique utilised for material characterisation, and more recently, measuring surface magnetisation with vortex beams has opened new avenues by utilising OAM beams for metrology. In this paper, we focus on extending the theoretical framework of unit order vortex beam reflection to spatially homogeneous magnetic surfaces, and derive expressions for the Goos-Hänchen (GH) and Imbert-Federov (IF) shifts. We calculate closed form expressions for the plane wave eigenpolarisations, polarisations which remain in the same vectorial direction after reflection, for both dielectric and homogeneous magnetic surfaces. These are found by extending the singularimetry formalism for dielectric surfaces, where the position of the phase vortex can be analytically approximated by taking into account the finite beam width, to homogeneous magnetic surfaces. From this we find the eigenpolarisations of the unit order vortex beam for reflection from both dielectric and homogeneous magnetic surfaces. We discuss with relation to the analytical forms of the Jones matrices for GH and IF shifts the additional reflection behaviour observed for homogeneous magnetic surfaces.
