  • Ha, Sangwoo; Sukhorukov, Andrey; Dossou, Kokou; Botten, Lindsay; De Sterke, C; Kivshar, Y (Optical Soc Amer, 2009)
    We demonstrate that the spatial profiles of both propagating and evanescent Bloch modes in a periodic structure can be extracted from a single measurement of an electric field at the specified optical wavelength. We develop ...
  • Liu, Wei; Sukhorukov, Andrey; Miroshnichenko, Ae; Poulton, Christopher; Xu, Zy; Neshev, Dn; Kivshar, Y (Amer Inst Physics, 2010)
    We study a plasmonic coupler involving backward (TM01) and forward (HE11) modes of dielectric waveguides embedded into an infinite metallic background. The simultaneously achievable contradirectional energy flows and ...
  • Ha, Sangwoo; Sukhorukov, Andrey; Dossou, Kokou; Botten, Lindsay; Lavrinenko, Andrei; Chigrin, Dmitry; Kivshar, Yuri (Optical Society of America, 2008)
    We suggest a novel and general approach to the design of photonic-crystal directional couplers operating in the slow-light regime. We predict, based on a general symmetry analysis, that robust tunneling of slow-light pulses ...
  • Mahmoodian, Sahand; Sukhorukov, Andrey; Ha, Sangwoo; Lavrinenko, Andrei; Poulton, Christopher; Dossou, Kokou; Botten, Lindsay; Mcphedran, Ross; De Sterke, C (Optical Society of America, 2010)
    We investigate the modes of double heterostructure cavities where the underlying photonic crystal waveguide has been dispersion engineered to have two band-edges inside the Brillouin zone. By deriving and using a perturbative ...
  • Gutman, N; De Sterke, C; Sukhorukov, Andrey; Botten, Lindsay (Amer Physical Soc, 2012)
    We show that a waveguide with multiple gratings can have a modal dispersion relation which supports frozen light. This means that light can be coupled efficiently to low group velocity modes of an optical waveguide or can ...
