Piezoelectric resonance controlled terahertz wave modulators
US 10,985,700 B2 — priority 19 July 2016 · filed 17 March 2020 · granted 20 April 2021 · active
Disclosed are various embodiments of a terahertz wave modulator. The wave modulator can include one or more layers of piezoelectric/ferroelectric single crystal or polycrystalline material. The crystalline material can be configured to resonate when a low-energy external excitation is applied. An incident terahertz waveform can be dynamically controlled when the incident terahertz waveform interacts with at least one layer of piezoelectric crystalline material while the at least one layer of piezoelectric crystalline material is resonating. The dynamic control of the incident terahertz waveform can be with respect to at least one of a phase shift and an amplitude modulation of the waveform.

Magnetoelectric-based systems and methods for modulating terahertz beams
US 10,866,485 B2 — priority 16 April 2018 · filed 16 April 2019 · granted 15 December 2020 · active
A system for modulating a terahertz beam includes a multiferroic nanoparticle heterostructure through which a terahertz beam can be propagated, and means for applying an external direct current (DC) magnetic field to the multiferroic nanoparticle heterostructure and the terahertz beam propagating through it, wherein application of the DC magnetic field modulates one or both of an amplitude and a phase of the terahertz beam.
