    Abstract: A THz radiation detector comprising a vertical antenna separated from a suspended platform by an isolating thermal air gap for concentrating THz radiation energy into a smaller suspended MEMS platform upon which a thermal sensor element is located. THz photon energy is converted into electrical energy via a thermally isolated air gap between plates of a coupling capacitor that couples energy from the antenna to the thermal sensor. The capacitor plates used for capacitive coupling of the received signal realize an electro-static actuator whereby the application of a DC bias varies the coupling capacitor gap. The DC bias causes the actuator to pull the suspended platform close to the antenna to reduce the capacitive gap, increasing the coupling capacitance, to touch the antenna array thus quickly discharging the heat induced in the sensor platform or to perform advanced readout operations, such as amplitude modulation and correlated double sampling.

    Abstract: A terahertz time-domain spectroscopic ellipsometry system includes a sample stage, a terahertz emitter configured to provide pulses of terahertz radiation with preselected polarization components to illuminate a sample on the sample stage along an incident direction, and a coherent terahertz detection system arranged to coherently detect pulses of terahertz radiation from the terahertz emitter along an emerging direction after at least one of reflecting from or passing through the sample. The sample stage is rotatable to vary a relative angle between the incident direction and the emerging direction, and the coherent terahertz detection system substantially maintains alignment for amplitude and polarization detection as the relative angle is varied.

    Abstract: The present invention relates to a trace gas detection system. At least one embodiment includes a frequency spectrum comprising a 1st comb and an enhancement cavity characterized by having a 2nd comb of spectral resonances. The enhancement cavity contains a sample gas for spectroscopic measurement. A dither mechanism is configured to modulate the relative spectral position between the combs at a dither frequency, fd. The dither mechanism, in conjunction with a feedback mechanism, stabilizes the location of said 1st comb lines with respect to the resonances of said 2nd comb over a time scale much greater than a dither period, Td=1/fd. A time-averaged output from the enhancement cavity is provided to a spectroscopic measurement tool, for example a Fourier transform spectrometer. The system is capable of detecting volatile organic compounds, endogenous compounds, and may be configured for cancer detection.
