More terahertz talks at the Ohio Innovation Sensor Summit

Session 2: Advances in THz Systems and Components (Pacey)
Moderator: Gilbert Pacey, Group leader CBRNE and THz Groups IDCAST/UDRI
The region of the electromagnetic spectrum known as terahertz (THz) has gained increasing interest due to availability of new sources and detection systems. Progress in ultrafast detection schemes, combined with femtosecond (1 fs ) 10-15 s) laser pumped nonlinear crystals, has brought the technique from specialized laboratories to realizing potential in mainstream applications. THz spectroscopy is a low power technique, facilitating nondestructive analysis of fragile materials; the energy in a THz pulse is less than typical background radiation present in the environment. The spectral range covers both rotational transitions from the microwave regime and vibrational modes from the infrared. This unique overlap of spectral features provides opportunities to analyze samples with completely new perspectives.
The session will feature new hardware and applications that will extend the utilization of THz. The State of Ohio has a significant investment and presence in THz with the IDCAST THz Collaborative Research Laboratory, HELIOS, Tracycer Diagnostic Systems, Lake Shore Cryogenics, and Wright State University’s THz Group.
