Quantum Optical Spectroscopy System for Materials in Extreme Environments
Abstract
This proposal describes the acquisition of a unique optical spectroscopy system designed to probe quantum effects of individual defects in semiconductor nanomaterials under carefully controlled environments. The system specifically includes (1) a widely-tunable, continuouswave, narrow-linewidth, visible laser for coherent photoexcitation spectroscopy and coherent quantum control along with (2) a closed-cycle optical cryostat providing an ultrahigh vacuum (UHV) sample environment, temperature control between 4 and 800 K, and a short optical working distance to facilitate diffraction-limited confocal fluorescence microscopy with sub-micron resolution. The proposed system will support detailed investigations of the electronic and chemical structure of quantum emitters in hexagonal boron-nitride (h-BN) as part of an ongoing ARO sponsored research project. More generally, it will enable a wide range of new capabilities of interest to ARO and DoD to study quantum defects in materials in the absence of surface contamination, including pristine diamond surfaces and nanodiamond particles for quantum sensors, and other emerging host materials such as thin films and semiconductor nanowires.
