“…More recently, Araneda et al demonstrated that the PSOI can lead to systematic wavelength‐scale errors when estimating the position of elliptically polarized emitters. [ 153 ] By directly capturing optical images of a single atom, a clear displacement between dipoles with opposite spin states can be observed. These findings may provide a novel way to give access to the local polarization states, which can be further used to sense physical quantities related to the polarization of light.…”

Photonic spin‐orbit interactions (PSOIs) in nanostructures have attracted much interest in nanophotonics, which provide a new paradigm to enhance light‐matter interactions and engineer the wavefronts of light on demand at the nanoscale. Many striking phenomena and functionalities, such as the photonic (quantum) spin‐Hall effect and the spin‐vortex conversion, have been demonstrated. Besides their underlying physics and manifestations, the experimental probing and imaging of PSOIs are also of great importance and highly demanded in not only the fundamental research but also the development of emerging PSOI technologies. Hence, in this review, the state‐of‐the‐art studies on the experimental observations and detections of PSOIs are systematically reviewed, including both the far‐field and near‐field methods. The respective advantages and difficulties of each method are stated and analyzed. The perspectives in probing PSOIs are also discussed.

“…The spatial variance properties of optical materials can also lead to optical spin-orbit interactions, particularly in the optical near-field, because the spin-orbit interactions become conspicuous at subwavelength scales and show the intrinsic coupling between the SAM and the position of light. [37][38][39] In addition, there exists a solution of bound states, which is quite robust against the interface roughness or other factors, at the interface between two media with positive and negative mass or energy gaps from the Dirac equation. For photons, there also exists a surface mode at the interface, for example, an evanescent plane wave.…”

Chiral spin textures are widely researched in condensed matter systems and have shown potential for use in spintronics and storage applications. Photonic counterparts of these textures are observed in various optical systems with broken inversion symmetry. Unfortunately, the resemblances are only phenomenological. This work proposes a theoretical framework based on the variational theorem to show that the photonic chiral spin textures in an optical interface originate from the system's symmetry and relativity. Analysis of the rotational symmetry in optical systems indicates that the conservation of the total angular momentum is preserved from the local variations of spin vectors. Specifically, although the integral spin momentum does not carry net energy, the local spin momentum distribution, which determines the local subluminal energy transport and minimization variation of the square of the total angular momentum, results in the chiral twisting of the local spin vectors. The findings of this study deepen the understanding of the symmetries, conservative laws, and energy transport in optical systems, reveal the similarities in the formation mechanisms and the geometries of photonic and condensed-matter chiral spin textures, and have potential applications in chiral and spin photonics.

“…In fact, in some cases, the amount of energy in the evanescent field exceeds what remains inside the fibre, so that the light is essentially guided outside the fibre. The ease with which these optical microfibres (OMF) or optical nanofibres (ONF) can be integrated into experimental setups means that they offer many advantages for applications in areas as diverse as optical sensing [7][8][9][10][11][12], atomic physics [13][14][15][16][17][18][19][20], photonics [21][22][23][24][25] and quantum optics [26][27][28][29][30][31].…”

Fabrication of optical nanofibre-based cavities using focussed ion-beam milling: a review

et al. 2020

Nanofibre-based optical cavities are particularly useful for quantum optics applications, such as the development of integrated single-photon sources, and for studying fundamental light-matter interactions in cavity quantum electrodynamics (cQED). Although several techniques have been used to produce such cavities, focussed ion beam (FIB) milling is becoming popular; it can be used for the fabrication of complex structures directly in the nanofibre. However, it is challenging to mill insulating materials with highly curved geometries and large aspect ratios, such as silica nanofibres, due to charge accumulation in the material. In this article, we highlight the main features of nanofibres and briefly review cQED with nanofibre-based optical cavities. An overview of the milling process is given with a summary of different FIB milled devices and their applications. Finally, we present our technique to produce nanofibre cavities by FIB milling. To overcome the aforementioned challenges, we present a specially designed base plate with an indium tin oxide (ITO)-coated Si substrate and outline our procedure, which improves stability during milling and increases repeatability.
