Hybrid Quantum Optomechanical Systems with Solid-State Artificial Atoms

Ongoing
Quantum Dot – Surface Acoustic Wave Microwave-to-Optical Transducers In this project, we focus on coupling nanoscale acoustic resonators with InAs quantum dot (QD) single photon sources (Fig. 1). At ultra-low temperatures, such as those in a dilution refrigerator, the acoustic resonators act as

Integrated Photonics

Ongoing
The Integrated Photonics Project utilizes heterogeneous materials integration to demonstrate novel optoelectronic devices such as semiconductor lasers, wavelength converters, and polarization rotators with compact form. We use materials including silicon, silicon dioxide, tantalum pentoxide, and

Nanostructure Fabrication and Metrology

Completed
This project develops semiconductor nanostructures, especially self-assembled quantum dots and photonic crystals, for a variety of applications including single photonics, laser diodes, and quantum optical metrology. It also develops quantum optical metrology based on other sources and detectors
