Abstract

See full text

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 the 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.
