Chip-Scale THz Generator

We propose to revolutionize the field of frequency-domain THznbsp;spectrometers by developing ~5nbsp;cm3 wide-band spectrometer with improved frequency accuracy, resolution and stability. Integration will also provide significant SWaP-C advantage compared to present solutions allowing deployment in small spacecraft platforms and other applications where low SWaP is crucial.Compared to presently available spectrometers, we expect significant improvements:10x weight reduction500x size reduction5x cost reduction1000x frequency accuracy improvement10x frequency resolution improvementGuaranteed long-term stability with built-in calibration until end-of-life (EOL)The core of the spectrometer is a stable THz signal generator providing continuous tuning with the ability to lock to a particular frequency with long-term stability. Said signal generator is a crosscutting technology that can be used in mm-wave/THz communication systems, frequency hopping devices and sensing application.
