Opportunities in optical microresonators: fundamentals and applications—Mar. 29

Join the Department of Materials Science & Engineering for a talk by Prof. Lan Yang on opportunities in optical micro resonators. This talk will cover ultra-high-quality whispering-gallery-mode (WGM) optical microresonators, which provide an unprecedented capability to trap light in a highly confined volume smaller than a strand of human hair.

Towards the fundamental limits of noise performance of III-V high electron mobility transistor microwave amplifiers—Mar. 23

Microwave amplifiers based on III-V high electron mobility transistors (HEMTs) are a key component of scientific instrumentation. Lower noise devices are of intense interest for applications in radio astronomy and quantum computing. In this talk, Minnich will discuss our efforts to identify and mitigate noise sources in HEMTs at cryogenic temperatures and thereby realize transistor amplifiers operating near the quantum noise limit.
