| Description | The University of Cambridge and Lancaster University (UK) researchers successfully developed a novel photonic modulator analyzed with Menlo Systems’ terahertz time-domain spectrometer. Terahertz radiation manipulation is an emerging research field with applications in communications, material sciences, biochemical spectroscopy or imaging. The development of novel, photonic materials to control THz polarization is an important step towards the manipulation of THz waves. Researchers from Cambridge and Lancaster designed a graphene-based 2D metamaterial that enables active manipulation of the THz polarization of a quantum cascade laser (QCL) with modulation rates in the MHz-range. Comparisons of experimental results to simulations have shown good agreement. Menlo Systems’ broadband THz-TDS system has been used for the successful measurements |
