To access the final edited and published work see http://pubs.acs.org/page/policy/articlesonrequest/index.htmlWe demonstrate experimentally all-optical switching on a silicon chip at telecom wavelengths. The switching device comprises a compact ring resonator formed by horizontal silicon slot waveguides filled with highly nonlinear silicon nanocrystals in silica. When pumping at power levels about 100 mW using 10 ps pulses, more than 50% modulation depth is observed at the switch output. The switch performs about I order of magnitude faster than previous approaches on silicon and is fully fabricated using complementary metal oxide semiconductor technologies.Reserva de todos los derechosCMOS photonicsAll-optical switchingSilicon nanocrystalsSilicon slot waveguidesTEORIA DE LA SEÑAL Y COMUNICACIONESArtículo10.1021/nl9041017Abierto1530-6992
