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.
Vapor Cells: The hearts of Quantum Standards
Turning a laser into a wavelength standard: quiet, stable, and accurate.
This architecture is a nationally-agreed-upon realization of the SI meter following the Bureau International des Poides et Mesures recommendations
VCT's Capabilities
We employ semiconductor manufacturing processes to be an end-to-end supplier of 1,000s of vapor cells and wavelength standards with enhanced functionality.
Enhanced functionality includes conducting, optical, and protective thin films patterend with nanometer-level precision.
Vapor Cells can be funcitonalized with various thin film coatings:
Electrical
Optical
Protective Coating
Application Spaces
Length Measurements
Optical Frequency Measurements
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
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
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
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.
