Product Details

Proton exchange method and metal diffusion method are the most common methods to prepare lithium niobate waveguide, due to the use of these two methods of the preparation of waveguide device waveguide diﬂer with the refractive index of substrate layer is small, light limit function is weak, and in the process of making the introduction of foreign ions can destroy the properties of lithium niobate crystal, so as to affect the performance of the waveguide. Based on the ridge waveguide structure of lithium niobate single crystal ﬁlm (LNO1), the refractive index difference between the core and the shell of the waveguide is greatly increased, and the optical limiting effect of the waveguide is enhanced, so the nonlinear effect of the lithium niobate waveguide can be improved. In addition, the lithium niobate ridge waveguide has a higher optical damage threshold and is suitable for high power frequency conversion devices.
