  • Active Near-Field Optical Microscopy 
    Le Gac Gaelle; Rahmani Adel; Seassal Christian; Picard Emmanuel; Hadji Emmanuel; Callard Segolene (IEEE, 2008)
    Near-field probe was used to tune the resonance wavelength of a linear cavity. Theoritical and experimental study are presented to show the effect of the probe material on the cavity resonance
  • Coupled dipole method for radiation dynamics in finite photonic crystal structures 
    Bordas Frederic; Louvion Nicolas; Callard Segolene; Chaumet Patrick; Rahmani Adel (American Physical Society, 2006)
    We present a coupled-dipole treatment of radiation dynamics in the weak-coupling regime in a finite threedimensional photonic crystal structure. The structure is discretized in real space and the self-consistent local field ...
  • Local Observation and Spectroscopy of Optical Modes in Active Photonic Crystal Microcavity 
    Louvion Nicolas; Gerard Davy; Mouette J; De Fornel Frederique; Seassal Christian; Letarte Xavier; Rahmani Adel; Callard Segolene (American Physical Society, 2005)
    We report the direct, room-temperature, near-field mapping and spectroscopy of the optical modes of a photonic-crystal microcavity containing quantum wells. We use a near-field optical probe to reveal the imprint of the ...
  • Local Observation and Spectroscopy of Optical Modes in Active Photonic Crystal Microcavity 
    Gerard Davy; Louvion Nicolas; Callard Segolene; Rahmani Adel; De Fornel Frederique; Mouette J; Letarte Xavier; Seassal Christian (Australia and New Zealand Third Sector Research, 2001)
    We report the direct, room-temperature, near-field mapping and spectroscopy of the optical modes of a photonic-crystal microcavity containing quantum wells. We use a near-field optical probe to reveal the imprint of the ...
  • Near-field and far-field analysis of an azimuthally polarized slow Bloch mode microlaser 
    Vo Thanh-Phong; Rahmani Adel; Belarouci Ali; Seassal Christian; Nedeljkovic Dusan; Callard Segolene (Optical Society of America, 2010)
    We report on the near- and far-field investigation of the slow Bloch modes associated with the G point of the Brillouin zone, for a honeycomb lattice photonic crystal, using near-field scanning optical microscopy (NSOM) ...
  • Nearfield observation of subwavelength confinement of photoluminescence by a photonic crystal microcavity 
    Louvion Nicolas; Rahmani Adel; Seassal Christian; Callard Segolene; Gerard Davy; De Fornel Frederique (Optical Society of America, 2006)
    We present a direct, room-temperature near-field optical study of light confinement by a subwavelength defect microcavity in a photonic crystal slab containing quantum-well sources. The observations are compared with ...
