We explore the integration of nanophotonic and plasmonic concepts with the silicon photonics platform. I will present hybrid plasmonic antennas on a silicon ring resonator and all-optical wavefront shaping in a multimode interference device.

We demonstrate ultrafast all-optical switching of local phase-change in plasmonic gold antenna-VO 2 hybrids exploting the strong resonant Near-Field enhancement on localized nanoscale regions.

Reduced cross section and strong plasmon confinement allows ITO antennas to be integrated at extremely high densities with no loss in performance due to long-range transverse interactions and to hold promise for extremely sub-wavelength SEIRS.

An on-chip technique for all-optical ultrafast control of silicon photonic elements was demonstrated by controlling transmission of SOI multimode interference-devices. Localized absorption by free carriers generated by ultraviolet pump pulses was used for achieving control.

Plasmonic nanoantennas as coherent perfect absorbers on top of SOI waveguides are explored using 3D-FDTD simulations. Losses of roughly 1% and extinction ratios better than 25 dB were achieved for modulator and switching applications.

Ultraviolet pump pulses generate a complex refractive index change in silicon, which we utilize for characterization and all-optical ultrafast control of waveguide elements. We demonstrate this damage-free technique on multimode interference devices.

We present the first angle-resolved measurements of spatial photon correlations that are induced by multiple scattering of light. The correlation relates multiple scattered photons at different spatial positions and depends on incident photon fluctuations.
