Shaping THz emission spectra by using sub-wavelength nanopatterned spintronic THz emitters

Bikash Das-Mohapatra, Reza Rouzegar, Evangelos Th. Papaioannou +2

We show in theory and experiment that in periodically patterned spintronic THz emitters (STE), charge dynamics can modify the emission spectrum in a well-controlled way. Characteri…
