Abstract
Stroboscopic control of polarization of THz radiation generated by femtosecond laser pulses in a spintronic source under acoustic resonance is investigated using numeric simulation methods. A possibility of changing the polarization direction of THz pulses by controlling the delay time between the acoustic oscillation triggering pulses and the laser pumping pulses is demonstrated with a composite multiferroic in the form of a TbCo2/FeCo magnetostrictive intermetallic heterostructure on a ferroelectric lead magnesium niobate–lead titanate (PMN-PT) substrate. It is shown that excitation of resonant oscillations by an alternating voltage of 0.15 V can allow controlling THz polarization in the range of up to 54° by stepless variation and up to 78° by stepped variation.
