Harmonic generation from silicon membranes at visible and ultraviolet wavelengths

In the last decade an impressive technological progress has been made towards the miniaturization process. Nowadays, structures with nanometric size are produced and integrated in different devices and applications, exploiting new light-matter interaction phenomena happening at this scale. One interesting material in nanotechnology is silicon. Nonlinear silicon photonic devices can emit light, modulate signals electro-optically and process data at speeds higher than electronic chips, and they are highly compatible with CMOS technology at low cost.
