Abstract
Abstract Two-dimensional (2D) materials are being actively researched due to their exotic electronic and optical properties, including a layer-dependent bandgap, a strong exciton binding energy, and a direct optical access to electron valley index in momentum space. Recently, it was discovered that 2D materials with bandgaps could host quantum emitters with exceptional brightness, spectral tunability, and, in some cases, also spin properties. This review considers the recent progress in the experimental and theoretical understanding of these localized defect-like emitters in a variety of 2D materials as well as the future advantages and challenges on the path toward practical applications.
Highlights
Two-dimensional (2D) materials exhibit strong light-matter interaction, giving rise to their large exciton binding energy, linear and nonlinear optical properties, and spin-valley coupling [1]
Many different types of quantum emitters have been discovered in recent years with exceptional properties including high brightness, high internal efficiency, spectral tunability, and first signatures of quantum interfaces to spin quantum memories
A focus on the following issues should give valuable basic scientific insights into these emitters and their mesoscopic quantum environment while illuminating the path toward practical applications in emerging quantum technologies: understanding disorder and decoherence to drive toward Fourier transform-limited linewidth in quantum emitters hosted by insulating [142]
Summary
Two-dimensional (2D) materials exhibit strong light-matter interaction, giving rise to their large exciton binding energy, linear and nonlinear optical properties, and spin-valley coupling [1]. They are a highly attractive platform for fundamental science as well as for applications. The seamless integration of 2D materials with a wide variety of photonic platforms offers opportunities for engineering nanoscale light-matter interaction [2,3,4]. Quantum emitters in 2D materials would provide a smaller footprint than most conventional solid-state quantum emitters, making them easier to integrate with existing photonic and optoelectronic structures with better light extraction and efficient modulation. This review discusses the recent advances made in the field of quantum optics of these localized emitters since their discovery
