Engineering & Integration of 2DM-Based Color Centers for Quantum Photonics

Color centers in two-dimensional materials (2DMs) are an emerging platform for quantum information applications. Several classes of 2DM-based color centers have been discovered with broadband single-photon emission (SPE) from ultraviolet to visible wavelengths with room temperature operation and spin-optical transitions. Unlike other wide bandgap materials like silicon carbide and diamond, the atomically thin nature of 2DMs naturally positions defects near a dangling bond-free surface leading to optimal surface SPE operation and maximal photon extraction efficiencies for ease of integration into optoelectronic and photonic devices. In this talk, we will present recent results on coupling of 2DM-based color centers to surface acoustic wave cavity phonons for single-photon modulation and control, and progress on engineering new types of emitters related to oxygen-based defects in hexagonal Boron Nitride.
