Programmable terahertz chip-scale sensing interface with direct digital reconfiguration at sub-wavelength scales.

ABSTRACT: The ability to sense terahertz waves in a chip-scale technology operable at room temperature has potential for transformative applications in chemical sensing, biomedical imaging, spectroscopy and security. However, terahertz sensors are typically limited in their responsivity to a narrow slice of the incident field properties including frequency, angle of incidence and polarization. Sensor fusions across these field properties can revolutionize THz sensing allowing robustness, versatility and real-time imaging. Here, we present an approach that incorporates frequency, pattern and polarization programmability into a miniaturized chip-scale THz sensor. Through direct programming of a continuous electromagnetic interface at deep subwavelength scales, we demonstrate the ability to program the
