Classical and Quantum Nanophotonics

About this Research Topic

Nanotechnology drives revolutionary transformations in our ability to control interactions between materials and light. The ability to engineer structures at a scale smaller than the wavelength of light enables new properties and functionalities otherwise not available in natural bulk optical materials.

The aim of this Research Topic is to cover the latest key findings and research updates for applications of nanotechnology to control light-matter interactions at the sub-wavelength scale. The focus will be given to advancements in nanophotonics in linear, nonlinear and quantum regimes. Prominent examples are :

(i) metasurfaces – two-dimensional arrays of designer resonant nanoscale elements whose optical response is defined by their geometry. The topic intends to cover the latest achievements on functional metasurface-based nanophotonic components and systems as well as the exploration of new frontiers in nonlinear interactions of metasurfaces with strong optical fields.

(ii) Topological states of light represent counterintuitive optical modes localized at boundaries of finite-size optical structures that originate from the properties of the bulk. Being defined by bulk properties, such boundary states are insensitive to certain types of perturbations, thus naturally enhancing the robustness of photonic circuitries. The topic intends to cover advancements in the miniaturization of topological states to the nanoscale which may facilitate on-chip integration of classical and quantum photonic devices.

(iii) 2D materials have attracted significant attention after the discovery of graphene. In the following years, reliable fabrication for a range of other 2D materials has been developed, including transition metal dichalcogenides, hexagonal boron nitride, black phosphorus and others. This topic will cover advances in 2D material applications to photonics. In this respect, 2D materials offer unique optical, electronic, spin and plasmonic properties facilitating strong electro-optical, linear and nonlinear optical interactions. (iv) Quantum nanophotonics has enabled the efficient generation of single photons and entangled photon pairs utilizing quantum dots, color centers and nonlinear optical approaches. In quantum nanophotonics, the brightness of photon sources can be strongly enhanced via light confinement in nano-waveguides and nano-resonators. Furthermore, generated photons can be coupled to integrated photonic circuits or metasurfaces for manipulation and processing. This topic intends to cover recent advances in nanophotonics used to generate and manipulate non-classical light.

We invite the submission of Original Research, Review, Mini Review, Perspective articles on themes including, but not limited to:

· Metamaterials and metasurfaces
· Nonlinear nanophotonics
· Topological nanophotonics
· Plasmonics
· Nanoresonators and antennas for light
· Quantum nanophotonics
· 2D materials
· Single-photon emitters.


Keywords: Nanophotonics, meta-optics, nonlinear optics, quantum light, 2D materials, topological photonics


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
