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

Modeling and Simulation of Nanofabrication (Archived)

Completed
While self-assembly is still in its relative infancy with respect to practical use, with much additional research required to reach maturity, the more widely utilized top-down methods will continue to require advances and modifications to improve current nanomanufacturing techniques. This modeling

Photonic Thermometry

Ongoing
Why do we need reliable temperature metrology? Temperature, the second most measured physical property after time and frequency, is indispensable to innumerable industries, military services, medicine, climate, and weather forecasts – precise, accurate, and rapid temperature metrology enables much
