    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 digital system has a dielectric core waveguide that is formed within a multilayer substrate. The dielectric waveguide has a longitudinal dielectric core member formed in the core layer having two adjacent longitudinal sides each separated from the core layer by a corresponding slot portion formed in the core layer The dielectric core member has the first dielectric constant value. A cladding surrounds the dielectric core member formed by a top layer and the bottom layer infilling the slot portions of the core layer. The cladding has a dielectric constant value that is lower than the first dielectric constant value.
