Abstract
We report a dual-tone source on thin-film lithium niobate for generating a tunable carrier frequency in the terahertz domain. The system achieves a stable carrier above 100 GHz, with sub-KHz linewidth and tunability over 5 GHz, offering a compact solution for integrated terahertz photonic systems.
