The first gas cell contains a dipolar gas and the second gas cell does not contain a dipolar gas. The system includes first and second transmit antennas coupled to the first and second gas cells, respectively, to provide first and second electromagnetic waves to the interior of the first and second gas cells, respectively; first receive antenna coupled to the first gas cell to generate a first signal indicative of an amount of energy in the first electromagnetic wave after travel through the first gas cell; second receive antenna coupled to the second gas cell to generate a second signal indicative of an amount of energy in the second electromagnetic wave after travel through the second gas cell; processor configured to calculate a background-free signal based on a difference between the first and second signals.

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: In described examples, a magnetic sensor includes a waveguide that encapsulates dipolar molecules. A mm-wave electromagnetic field is launched into the waveguide, travels through the dipolar molecules, and is then received after passing through the dipolar molecules. The frequency of the mm-wave electromagnetic signal is swept across a range that includes an intrinsic quantum rotational state transition frequency (Fr) for the dipolar molecules. Absorption peaks in accordance with the Zeeman effect are determined. A strength of a magnetic field affecting the magnetic sensor is proportional to a difference in the frequencies of the absorption peaks.

Abstract: A clock generator includes a hermetically sealed cavity and clock generation circuitry. A dipolar molecule in the hermetically sealed cavity has a quantum rotational state transition at a fixed frequency. The clock generation circuitry generates an output clock signal based on the fixed frequency of the dipolar molecule. The clock generation circuitry includes a detection circuit, a reference oscillator, and control circuitry. The detection circuit generates a first detection signal and a second detection signal representative of amplitude of signal at an output of the hermetically sealed cavity responsive to a first sweep signal and a second sweep signal input to the hermetically sealed cavity. The control circuitry sets a frequency of the reference oscillator based on a difference in time of identification of the fixed frequency of the dipolar molecule in the first detection signal and the second detection signal.

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.
