Cascading of second-order nonlinear effects leads to an effective third-order nonlinearity. In addition to the macroscopic electric field at the intermediate frequencies another term has to be taken into account which is due to the locality of the intermediate polarization sources. Combining the correction terms at the three intermediate frequencies gives rise to a third-order susceptibility tensor, which exhibits the same symmetry properties as an intrinsic susceptibility. This particularly applies to the contributions from the rectified and the second-harmonic fields to the degenerate susceptibility.

“…Mode matching in this case is simplified compared to DFG pumped at 780 nm, since all input wavelengths are in the same band and can be launched into a single port.

In this paper, we demonstrated for the first time variable 1.5μm wavelength conversion through cascaded second order nonlinear processes "SHG+DFG" by fan-out grating in lithium niobate waveguide. We fabricated the waveguide by annealed proton exchange in periodically poled LiNbO 3 (PPLN). The device used in this experiment is 4 cm long, has a QPM period from 14.8μm to 15.2μm, waveguide width of 12μm, proton exchange depth of 0.7μm, and was annealed for 32h at 350℃. After proton exchange in pure benzoic acid using a SiO 2 mask, the substrate was annealed in an oxygen atmosphere. The wavelength of signal light was set at 1551.3 nm. The wavelengths of tunable pump lights we used in experiment were 1543.2 and 1556.2 nm, and the corresponding grating periods were 14.87 μ m and 15.03 μ m, respectively. The temperature was set at 100.5℃ to avoid photo refractive damage and to match the QPM peaks to the pump wavelengths. The conversion efficiency was about 10dB to be expected with the pump power 175mW in a similar device with a slightly different QPM period and operated at 125℃.
