“…The metallic hologram design presented above enables the realization of a compact and integrated OAM detection scheme, but only works for one specific OAM state. Recently a novel scheme enables multiple OAM states detecting was reported with circular slot plasmonic antenna [60]. Figure 22 shows the SEM image of the fabricated sample and experimental configuration.…”

Abstract:Recently there is an increasing interest in complex optical fields with spatially inhomogeneous state of polarizations and optical singularities. Novel effects and phenomena have been predicted and observed for light beams with these unconventional states. Nanostructured metallic thin film offers unique opportunities to generate, manipulate and detect these novel fields. Strong interactions between nano-metallic surfaces and complex optical fields enable the development of highly compact and versatile functional devices and systems. In this review, we first briefly summarize the recent developments in complex optical fields. Various nano-metallic surface designs that can produce and manipulate complex optical fields with tailored characteristics in the optical far field will be presented. Nano-metallic surfaces are also proven to be very effective for receiving and detection of complex optical fields in the near field. Advances made in this nascent field may enable the design of novel photonic devices and systems for a variety of applications such as quantum optical information processing and integrated photonic circuits.

“…Conventional approaches use bulky free space components, such as wave-plates and polarizing analyzers, diffraction gratings [119,120], spatial light modulator [121][122][123], and interference measurement [124][125][126][127]. Spin-dependent metasurfaces, on the contrary, show a strong capability to generate and detect the angular momentum of light [113,114,[128][129][130]. For example, a detector metasurface designed by holographic approach was proposed [128].…”

Optical spin-Hall effect (OSHE) is a spindependent transportation phenomenon of light as an analogy to its counterpart in condensed matter physics. Although being predicted and observed for decades, this effect has recently attracted enormous interests due to the development of metamaterials and metasurfaces, which can provide us tailor-made control of the light-matter interaction and spin-orbit interaction. In parallel to the developments of OSHE, metasurface gives us opportunities to manipulate OSHE in achieving a stronger response, a higher efficiency, a higher resolution, or more degrees of freedom in controlling the wave front. Here, we give an overview of the OSHE based on metasurface-enabled geometric phases in different kinds of configurational spaces and their applications on spin-dependent beam steering, focusing, holograms, structured light generation, and detection. These developments mark the beginning of a new era of spin-enabled optics for future optical components.

“…8 Many recent articles concerning such twisted beams suggest a capacity for one or two orders of magnitude increase in data transfer rate. [9][10][11][12] Such aspirations reflect the fact that topological charges with a magnitude of more than 100 have been reported to date. 13 Moreover, the grounds for such advances in communication are not limited to simple photon transfer, but may also exploit quantum entanglement between separate photons, with recent work achieving the entanglement of a second degree of freedom: the orbital angular component in addition to the spin state.…”

Descriptions of optical beams with structured wavefronts or vector polarizations are widely cast in terms of classical field theory. The corresponding fully quantum counterparts often present new insights into what is physically observed, and they are especially of interest when tackling issues such as entanglement. Similarly, when determining angular momentum densities, it appears that the separate roles of photon spin and beam topological charge can only be satisfactorily addressed within a quantum framework. In some such respects, the quantum versions of theory might be considered to introduce an additional layer of complexity; in others, they can clearly and very substantially simplify the theoretical representation. At the photon level, the fully quantized descriptions of topologically structured and singular beams nonetheless raise important fundamental questions and puzzles, whose resolution continue to invite attention. Many of the mechanistic interpretations and predictions (those that appear to be supported by a true congruence between classic and quantum optical descriptions, essentially conflating electromagnetic field and state wavefunction concepts) can lead to theoretical pitfalls. This paper highlights some physical implications that emerge from a fully quantum treatment of theory.
