Abstract:  Traditional electromagnetic (EM) spectral sensors using integrated circuit technologies (e.g.
automotive radars, security imagers, cameras, etc.) are normally based on wave scattering or absorption
by macroscopic objects at remote distance; the operations are also not specific in wave frequencies. In
the past couple of years, a new paradigm of chip-scale EM spectral sensing emerges with features
complementary to the above: they utilize various modalities of interactions between EM waves with highprecision frequency control and microscopic particles (molecules, atoms, etc.) in close proximity to the
chip. This progress is enabled by the recent advances of silicon devices and processes, especially the
increase of circuit operation frequencies into the terahertz regime. Chip-scale sensing and metrology
systems with new capabilities, higher performance and unprecedented affordability now become possible.
Examples include THz gas spectroscopy sensors, on-chip “atomic-clock-grade” frequency references,
room-temperature CMOS-quantum magnetometers, etc. This talk will present the basic physics of a few
types of wave-matter interactions, key enabling technologies, as well as the designs and prototypes of
chip systems. We will also discuss their potential applications in bio-chemical analysis, wireless networks,
PNT (positioning, navigation & timing), security and so on.
