School of Physics CM/AMO/GTRI Seminar - Dr. Matthew Hummon

Precision spectroscopy in microfabricated vapor cells for compact atomic clocks.

Precision spectroscopy of warm atomic vapors is a core technology for quantum sensors devices.  For these devices to be adopted more broadly in industrial and commercial applications, transferring the spectroscopic techniques from the laboratory to an environmentally robust and manufacturable platform is desirable.  I will discuss our group’s work on integrating laser spectroscopy of warm atomic vapors with single-mode waveguide nanophotonic structures.  Additionally, I will discuss the development of two different compact optical clocks based on microfabricated vapor cells. One is based on a two-photon transition in rubidium, and the second is based on narrow line spectroscopy in warm strontium vapors.
