Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

An optically pumped ultrasensitive broadband terahertz (THz) wave modulator based on polyvinyl alcohol (PVA) film on Si wafer was demonstrated in this work. The THz time domain spectroscopy ...

Researchers use graphene metamaterial to create terahertz modulators with record depth and speed, opening new possibilities for communications, imaging, and sensing. (Nanowerk News) Researchers at the ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.200093 discusses dual epsilon-near-zero effect assisted broadband electro-optic modulation. With the continuous and rapid ...
