We calculate the TWM gain for arbitrary crystal cut and optimize the energy exchange. For the (111) cut, by choosing an appropriate coordinate system, we obtain a simple analytical solution for the components of the coupling tensor which allows us to optimize analytically the TWM gain with respect to the grating orientation and the initial light polarization. |
