    Abstract: A millimeter wave molecular sensor system is provided. The system includes a physics cell configured to contain a sample, a directional coupler configured to receive input millimeter waves, partition the input millimeter waves into a pump signal and a probe signal for transfer to the physics cell, a receiver configured to receive millimeter waves exiting the physics cell, a Faraday rotator coupled between a pump transmitter and the physics cell, and a coupling iris coupled between the Faraday rotator and the physics cell, configured to pass millimeter waves having a first polarization into the physics cell. The Faraday rotator includes a Faraday material, and an electronic device configured to apply a magnetic field to the Faraday material parallel to a propagation direction of the millimeter waves such that when the electronic device is activated, the Faraday material rotates a polarization of the millimeter waves passing through the Faraday rotator.

    Abstract: A compact mmW spectroscopy cell system for detecting volatile organic compounds (compounds) in a gas. The system includes a gas collection chamber, an input buffer cavity for receiving the gas from the gas collection chamber, pumping devices to pass the gas from the buffer cavity to an absorption cell and maintain pressure, and a transceiver connected to the cell. The transceiver interrogates the absorption cell filled with the gas by passing a high frequency electromagnetic signal and sweeping the signal to generate an absorption spectra which is compared to a spectroscopy database for detecting the compounds in the gas. The absorption cell, collection chambers, and pumping devices are fabricated with standard CMOS processing techniques at chip and wafer scale. The transceiver bonded to the absorption cell with chip scale integration.

    Abstract: A stackable molecular spectroscopy cell includes a hollow body, a first cap affixed to a first surface of the hollow body, covering a first opening in the hollow body, and a second cap affixed to a second surface of the hollow body, covering a second opening in the hollow body, and forming a sealed cavity within the hollow body. The sealed cavity contains a dipolar gas having a pressure of less than 0.5 mbar. The stackable molecular spectroscopy cell also includes a metal layer covering an inner surface of the hollow body and an inner surface of the first and second caps, including a first aperture in the metal layer covering the inner surface of the first cap and a second aperture in the metal layer covering the inner surface of the second cap.
