We are developing core technology tools to enable chip-scale standards that realize a broad range of base and derived SI units in compact, manufacturable packages.


NIST on a chip

The NIST on a Chip project in the Atomic Devices and Instrumentation group is focused on the development of compact, manufacturable, low power, SI-traceable calibration instruments using atomic vapor cells. We anticipate such devices could be broadly used in industrial settings for in-situ calibration of instruments and systems. This technology is inspired by past work on chip-scale atomic clocks, which were invented at NIST and have been successfully commercialized. Specifically we are developing:

  1. Length standards based on precision optical spectroscopy of atomic vapors confined in a cell
  2. Time standards based on miniaturized cold atom technology
  3. Current standards based on accurate magnetometry
  4. Temperature standards using Doppler thermometry

A presentation summarizing the NIST on a Chip program made to the NIST Visiting Committee on Advanced Technology can be found here.
