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 5–100 μm, revealing substantial slab waveguide behavior at the longer wavelengths.
