A terahertz (THz) source based on hybrid Opt‐THz fiber, which is made of concentric central optical fiber and external Terahertz fiber, was proposed. With the enhanced second order nonlinearity in the central optical fiber, THz waves are distributed through difference frequency by high‐power optical pump laser. The external THz fiber will be designed with hollow fiber structure, and the THz waves are propagated and accumulated along the THz fiber. The simulation shows that the maximum THz power can reach ~4.8 mW after a 13.7 m optimal fiber length. The proposed THz source will be able to compete with existing THz sources in terms of power, compactness, frequency tunability and room‐temperature operation.
