Designing the Nanoworld: Nanostructure, Nanodevices, and Nano-optics

Ongoing
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the

Frequency Conversion Interfaces for Photonic Quantum Systems

Ongoing
Our research on quantum frequency conversion follows two main tracks. First, we combine relatively mature frequency conversion technology based on periodically-poled lithium niobate waveguides with quantum light generated by single semiconductor quantum dots in proof-of-principle experiments that

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

Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have
