Vapor Cell Technologies

Manufacturing the hearts of quantum technologies.

What is a Vapor Cell? A Vapor Cell is a box of atoms or molecules. Vapor Cells can be measured with a laser and can form the hearts of many quantum sensors and standards. As atoms are fundamental structures composed of fundamental particles, their energy level structures form the basis of many practical realizations of absolute frequencies and wavelengths.

Interferometry

Interferometry can sense distances with sub-nanometer precision; employing a wavelength standard can make interferometric measurements accurate at the part-per-billion level

Fiber Optic Sensing Icon

Fiber Optic Sensing

Fiber optic sensors can measure stress, strain, vibration, and temperature with extreme sensitivity along a cheap optical fiber. Wavelength standards can make fiber interrogators accurate and stable over years equating to trustworthy structural health monitoring applications in bridges, buildings, and vehicles.

FTIR Spectroscopy Icon

FTIR Spectroscopy

Fourier-Transform Infrared (FTIR) Spectroscopy employs a laser to measure the displacement of a scanning interferometer. Wavelength standards make this equipment stable over the course of years and accurate, never needing a calibration.

Coherent Communications Icon

Coherent Communications

Coherent optical communication can amplify incoming optical signals up to the photon shot noise limit improving sensitivity 1,000X over IM/DD schemes. Coherent optical communications can be employed underwater, in free space, or in fiber.
