We demonstrate terahertz (THz) wave generation by wavelength conversion in a ridge-type/bulk periodically poled lithium niobate (RT-/bulk-PPLN) under almost the same experimental conditions. When using the RT-PPLN, the ridge structure works as a slab

We designed and developed a chirped periodically poled LiNbO3 ridge waveguide device to broaden a quasi-phase-matching bandwidth. We achieved a broad bandwidth of second harmonic generation of 4.6 nm in a telecommunication band.
