Opt Express 18:19831-43. 2010..A non resonant negative index material with isotropic polarization in the visible region is also proposed using this waveguide structure...
- All-optical ultrafast control of beaming through a single sub-wavelength aperture in a metal filmMohamed A Swillam
Department of Physics and Institute for Optical Sciences, University of Toronto, Toronto, M5S 1A7 Canada
Opt Express 19:7856-64. 2011..Both the grating and the beaming effect are shown to decay on a picosecond time-scale. An on-off contrast of 5 dB is obtained for the beaming, with a divergence angle of only 2.4 degrees...

Opt Express 20:12473-86. 2012..55 µm for different polarizations. We analyze and simulate the structure using the FDTD method. The proposed device can be utilized in integrated chips for optical signal processing and optical computations...
- Hybrid orthogonal junctions: wideband plasmonic slot-silicon waveguide couplersBenedict Lau
Edward S Rogers Sr Department of Electrical and Computer Engineering, University of Toronto, Toronto, Canada
Opt Express 18:27048-59. 2010..This center wavelength can be controlled by varying the silicon waveguide width. Theoretical analysis is in good agreement with FDTD simulated results, and experimental results. The fabrication procedure is also presented and discussed...
