Quadratic Solitons in Cubic Crystals


Starting from the Maxwell’s equations and without resort to the paraxial approximation, we derive equations describing stationary (1+1)-dimensional beams propagating at an arbitrary direction in an optical crystal with cubic symmetry and purely quadratic (χ) nonlinearity. The equations are derived separately for beams with the TE and TM polarizations. In… (More)
