Abstract: |
We present numerical results that describe
how to engineer the radiation pattern of the second harmonic (SH) signal
generated by AlGaAs on aluminum oxide all-dielectric
nanoantennas. The SH beam divergence is minimized
by coherent forward and backward scattering of the radiation emitted at
grazing angles from the optical antenna toward a concentric grating grown on the
aluminum oxide substrate, whereas the symmetry of the SH mode is converted by
introducing a suitablydesigned phase shift. The
parameters of the structure are optimized through extensive numerical
simulations and design guidelines for fabrication are provided. |
