Terahertz wave generation and propagation in thin-film lithium niobate produced by crystal ion slicing
Abstract
Terahertz phonon-polariton generation and real-space imaging with femtosecond optical pulses are demonstrated in a 10-μm-thick film of single-crystalline lithium niobate that was generated through crystal ion slicing. The film dispersion properties were characterized throughout the polariton wavelength range of 5-100μm, revealing substantial slab waveguide behavior at the longer wavelengths.
