Figure 3 | Dynamical tuning of nonlinear diffraction.  a, Demonstration of the dynamic modulation of the splay angle through the application of opposite-direction in-plane electric fields along the grating stripe direction. The variation in the splay angle is estimated to reach a maximum of ±  at the maximum electric field strength of ±0.06 V/μm (attributed to instrumental range limitations). b, Simulated and experimental diffraction patterns of SH signals under illumination with horizontally polarized and vertically polarized light.
