Project Description 

The associate's work entails the design, fabrication and testing of advanced optical frequency references based on two-photon transitions in Cs atoms.  The associate fabricates small silicon/glass microfabricated Cs vapor cells, and sets up a laser to interrogate the atoms in these cells and measure the stability of the resulting optical standard. Some of their responsibilities include but are not limited to fabricating alkali vapor cells, carrying out experimental spectroscopy on vapor cells, and analyzing data to understand limitation to performance of optical reference.

Research Interests

I am interested in Atomic, Molecular, and Optical (AMO) physics, Condensed Matter Physics, and Nanotechnology. In NIST, my primary focus is on advancing next-generation quantum technologies through the development of chip-scale atomic devices and micro-fabricated vapor cells, as well as testing the performance of optical frequency references for micro-fabricated quantum atomic sensors—such as optical atomic clocks, gyroscopes, and magnetometers—for timekeeping, navigation, and precision sensing, driven by innovations in quantum metrology and frequency standards.
