Quantum Emitters in Optically Resonant Nanostructures

About this Research Topic

Nanostructures supporting electromagnetic resonances in optical frequency are of great interest to the nanophotonic community in recent years due to their ability to manipulate and enhance light at subwavelength/nanoscale dimensions. These nanostructures are essential building blocks for the miniaturization of components and interconnect of photonic circuits where conventional optical components such as lenses or mirrors are no longer functional. One of the important topics in this nanophotonic branch is the engineering of light-matter interaction when coupling quantum emitters to optical resonances in nanostructures. This leads to fascinating phenomena such as fluorescence enhancement via Purcell effect, out-coupling radiation tailoring, strong coupling regime physics (exciton-polariton, plasmon-polariton, phonon-polariton…), active topological photonics (topological laser, photonic edge states …), and non-hermitian photonics (Bound state In Continuum, Exceptional Points), etc. These phenomena imply many applications such as light-emitting devices, nanolasers, quantum information processing, quantum communication, sensors, and so on.  


This Research Topic aims to focus on the study of the interaction (both in weak and strong regimes) between optical resonant modes in nanostructures and quantum emitters. This will strengthen our fundamental understanding of how quantum emitters such as semiconductor quantum dots, quantum wells, organic molecules, two-dimensional dichalcogenides, perovskites, etc. behave when they are placed in a resonant nanostructure. Both near-field coupling and the resulting far-field out-coupling radiation are within the scope of this Research Topic. Another aim is to explore new design principles/approaches to effectively obtain resonant nanostructures with desired optical functionality. One example is to use deep-learning/neural networks to design arbitrary structures instead of the conventional simulation approach. 


In this Research Topic, we welcome experimental and theoretical papers covering the broad context of the interaction between resonant nanostructures and quantum emitters such as: 

• Enhanced fluorescence/radiation control using resonant nanostructures

• Nanostructured light-emitting devices (LED, laser)

• Strong coupling regime of the quantum emitter with resonant nanostructures

• Single-photon emitter behavior in resonant nanostructures

• Bose-Einstein condensation and polariton lasing in an optical nanocavity

• Topological photonics in optical lattices 

• Bound state in the continuum as a cavity for nanolasers 

• Exceptional Points physics in non-hermitian photonic systems



Keywords: Quantum emitter, dielectric nanoantenna, plasmonic nanoantenna, resonant nanostructures, colloidal quantum dot, Mie theory, bound state in continuum (BIC), nanolasers


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.
