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: Methods for depositing a measured amount of a species in a sealed cavity. In one example, a method for depositing molecules in a sealed cavity includes depositing a selected number of microcapsules in a cavity. Each of the microcapsules contains a predetermined amount of a first fluid. The cavity is sealed after the microcapsules are deposited. After the cavity is sealed the microcapsules are ruptured to release molecules of the first fluid into the cavity.

Abstract: A method includes forming a plurality of layers of an oxide and a metal on a substrate. For example, the layers may include a metal layer sandwiched between silicon oxide layers. A non-conductive structure such as glass is then bonded to one of the oxide layers. An antenna can then be patterned on the non-conductive structure, and a cavity can be created in the substrate. Another metal layer is deposited on the surface of the cavity, and an iris is patterned in the metal layer to expose the one of the oxide layers. Another metal layer is formed on a second substrate and the two substrates are bonded together to thereby seal the cavity.

Abstract: A method of aligning optical signals in a fiber optic switching device with one or two phase light modulators (PLMs) includes configuring the phase elements of the PLMs with first initial settings, to direct an optical signal from an input fiber to an output fiber. An initial position displacement of a center of the signal image from a center of the output fiber is estimated. Corrected settings for the phase elements are calculated so that when the corrected settings are applied to the phase elements, a corrected signal image of the optical signal has a corrected position displacement from the center of the output fiber that is less than the initial position displacement. A fiber optic switching device has processing circuitry and a memory component configured to execute steps of the method of aligning the optical signals.
