Abstract

We investigated the THz generation from a 500 nm lithium niobate thin film by optical rectification of femtosecond pulses. A comparison between the numerical studies and polarization-resolved measurements of the THz signal reveals an enhancement of the nonlinear response in the thin film due to the phonon-driven ionic contributions. Our results pave the way to the development of new integrated THz emitters and detectors operating up to 8 THz based on nanophotonic structures, such as nanowires and metasurfaces, realized in the thin film lithium niobate platform.
