Wafer-Level Fabrication of Alkali Vapor Cells Using In-Situ Atomic Deposition

December 14, 2020
Author(s)
Douglas Bopp, Vincent N. Maurice, John Kitching
We demonstrate a new technique for filling microfabricated silicon and glass cavities with alkali vapors at the wafer-scale. A single etched silicon wafer contains an array of cavities containing alkali precursor materials offset laterally from the cell

Atomic flux circuits

February 23, 2020
Author(s)
Douglas Bopp, Ellyse Taylor, Khoa Le, Susan Schima, Matthew Hummon, John Kitching
Atomic vapors are a crucial platform for precision metrology but in their simplest implementation, a thermal vapor, the intrinsic optical resonances are broadened due to the random and isotropic thermal motion of the atoms. By structuring the container of

Ultranarrow linewidth photonic-atomic laser

January 8, 2020
Author(s)
Wei Zhang, Liron Stern, David R. Carlson, Douglas G. Bopp, Zachary L. Newman, Songbai Kang, John Kitching, Scott Papp
Lasers with high spectral purity can enable a diverse application space, including precision spectroscopy, coherent high-speed communications, physical sensing, and manipulation of quantum systems. Already, meticulous design and construction of bench Fabry

Chip-scale atomic diffractive optical elements

December 31, 2018
Author(s)
Liron Stern, Douglas G. Bopp, Susan A. Schima, Vincent N. Maurice, John E. Kitching
Atomic systems have long provided a useful material platform with unique quantum properties. The efficient light-matter interaction in atomic vapors has led to numerous seminal scientific achievements including accurate and precise metrology 1-3 and

Photonic chip for laser stabilization to an atomic vapor at a precision of $10^{-11}$

April 11, 2018
Author(s)
Matthew T. Hummon, Songbai Kang, Douglas G. Bopp, Qing Li, Daron A. Westly, Sangsik Kim, Connor D. Fredrick, Scott A. Diddams, Kartik A. Srinivasan, John E. Kitching
We perform precision spectroscopy of rubidium confined in a micro-machined, 27~mm$^3$ volume, vapor cell using a collimated free space 120~$\bm{\mu}$m diameter laser beam derived directly from a single mode silicon nitride waveguide. With this optical
