  • Patent number: 10520365
    Abstract: A detector for terahertz electromagnetic waves includes a terahertz optomechanical transducer to transform an incident electromagnetic wave, having a terahertz frequency within a terahertz frequency band, into a measurable mechanical response; and a detection device for detecting an output signal. The terahertz optomechanical transducer includes a first element and an opposite element forming with the first element a capacitive gap.
    Type: Grant

  • Patent number: 7152007
    Abstract: A system for investigating a sample, the system including a detector having non-linear current voltage characteristics and being configured to mix two radiation signals having frequencies in the range from 25 GHz to 100 THz, one of the signals being a local oscillator signal and the other signal being a sample signal carrying information about the sample being investigated, the system further having a quantum cascade laser for providing at least the local oscillator signal.

  • Publication number: 20060153262
    Abstract: A laser comprising: a substrate comprising a bulk region and a conducting layer; an active region (11) comprising a quantum cascade structure provided on a first surface of the substrate (12) such that said active region (11) is electrically connected to said conducting layer; first and second contacts (16, 17) being disposed on opposite sides of said active region (11); and an active region contact (31) provided to said active region (11) such that a potential may be applied between said active region contact (31) and said first and second contacts (16, 17) to cause said active region (11) to lase.
