HIGHLIGHTS
- who: Klaas-Jan Tielrooij from the (UNIVERSITY) have published the article: Milliwatt terahertz harmonic generation from topological insulator metamaterials, in the Journal: (JOURNAL)
- what: The authors demonstrate room-temperature terahertz harmonic generation in a Bi2Se3 topological insulator and topological-insulator-grating metamaterial structures with surface-selective terahertz field enhancement. The authors focus this light onto a sample and measure the transmitted waveform using electrooptic sampling (EOS) with 100 fs laser sampling pulses and a 2 mm thick ZnTe nonlinear crystal. In Fig 1c the authors show the power of the third-harmonic signal for increasing . . .
