Optimization of the NanoGate performance. (a) Surface profile after TG excitation consisting of a long-range thermal distortion and a short-range thermal grating. (b) Theoretical diffraction efficiency from the surface profile shown in (a). (c) Diffracted intensity in the first order versus surface amplitude for different surface properties. (d) Diffraction efficiency versus surface amplitude for optimized structures at different TG periods. |
