Periodic Poled Lithium Niobate Ridge Waveguide Devices
Classification:
The most commonly used preparation methods of lithium niobate optical waveguides are proton exchange method and metal diffusion method, because the refractive index difference between the waveguide and the substrate layer of the waveguide device prepared by these two methods is small, the limiting effect on light is weak, and the foreign ions introduced in the production process will destroy the properties of the lithium niobate crystal itself, thus affecting the performance of the waveguide. The ridge waveguide structure based on lithium niobate single crystal thin film (LNOI) greatly increases the refractive index difference between the core and shell of the waveguide, so the optical confinement effect of the waveguide is enhanced, which can improve the nonlinear effect in the lithium niobate waveguide. In addition, the optical damage threshold of the lithium niobate ridge waveguide is higher, which is suitable for the production of high-power frequency conversion devices.
