Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate

Photonic Radiometry

Ongoing
Meeting the needs of the photonics industry and anticipating emerging technologies requires investigation and development of improved measurement methods and instrumentation. This project develops state-of-art, absolute microfabricated thermal detectors with absorber coatings consisting of carbon

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

Single Photonics and Quantum Information

Ongoing
One of the activities in this group is the development of single photon technologies for quantum information science and technology. We work closely with the Nanostructure Fabrication and Metrology Project on the generation of novel non-classical states of light and the detection of single photons
