THz photonics: bridging the “gap” and beyond
Abstract: Historically, THz technologies were mainly used within the astronomy
community for searching far-infrared radiation (cosmic background), and the
laser fusion community for the diagnostics of plasmas. Since the first
demonstration of THz wave time-domain spectroscopy in the late 80’s, there has
been a series of significant advances (particularly in recent years) on the
development of intense sources and sensitive detectors.
THz photonics involves the interaction of intense femtosecond laser pulses with
matters (solid, liquid, air, and plasma). I will review THz wave generation and
detection techniques using air as emitter and sensor. Also, I will explore the
remaining challenges and future opportunities for this rapidly evolving area of
research that transcends the "gap" once existing between optics and electronics.
I will also highlight their potentials, including for the national security applications.
