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

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

GaN Nanowire Growth

Ongoing
Selective epitaxy: We have demonstrated that the diameter and placement of nanowires can be controlled by using silicon nitride (SiNx) masks on top of MBE-grown buffer layers (see figure). With electron beam lithography, several patterns with 3 mm die size that provide over 100,000 controlled

Waveform Metrology Project

Ongoing
Optical measurement techniques: NIST uses the electro-optic sampling (EOS) technique to measure the vector response of photodiodes and provide phase traceability for commercial instrumentation, such as large-signal network analyzers, lightwave component analyzers, vector signal analyzers
