The frontier of information processing lies in nanoscience and nanotechnology research. At the nanoscale, materials, and structures can be engineered to exhibit interesting new properties, some based on quantum mechanical effects. Our research focuses on developing nanofabrication technology at the few-nanometer length scale. We use these technologies to push the envelope of what is possible with photonic and electrical devices, focusing in particular on superconductive and free-electron devices. Our research combines electrical engineering, physics, and materials science and helps extend the limits of nanoscale engineering.

Superconducting Devices

We design and fabricate superconducting nanowire single photon detectors (SNSPDs). SNSPDs are appropriate for many applications because they have low jitter, a fast reset time and good sensitivity to infrared light. Thus, we are working on several research projects to...
