• Integrated metamaterial surface-emitting antenna for beam steering applications 

      Ginel-Moreno, Pablo; Sánchez-Postigo, Alejandro; de-Oliva Rubio, José; Hadij-ElHouati, Abdelfettah; Ye, Winnie N.; [et al.] (2021-12)
      Integrated optical antennas are relevant devices for the development of next-generation LIDAR systems. Here we experimentally demonstrate a new topology to implement long antennas in silicon-on-insulator platform. The ...
    • Mid-infrared Suspended Waveguide Platform and Building Blocks 

      Wanguemert-Perez, Juan Gonzalo; Sánchez-Postigo, Alejandro; Soler-Penades, Jordi; Ortega-Moñux, Alejandro; Nedeljkovic, Milos; [et al.] (2018-06-05)
      In this work we present our recent progress in the development of a platform for the mid-infrared wavelength range, based on suspended silicon waveguide with subwavelength metamaterial cladding. The platform has some ...
    • Subwavelength-engineered metamaterial devices for integrated photonics 

      Sánchez-Postigo, Alejandro; Ginel-Moreno, Pablo; Pereira-Martín, Daniel; Hadij-ElHouati, Abdelfettah; Luque-González, José Manuel; [et al.] (2022)
      The engineering of subwavelength grating metamaterials has become an essential design strategy in silicon photonics. The lithographic segmentation of integrated waveguides at the subwavelength scale enables the synthesis ...
    • Subwavelength-grating metamaterial integrated devices for the near- and mid-infrared wavelengths 

      Sánchez-Postigo, Alejandro; Wanguemert-Perez, Juan Gonzalo; Ortega-Moñux, Alejandro; Halir, Robert; Pereira-Martín, Daniel; [et al.] (2021)
      The subwavelength patterning of planar structures is now widely used in silicon photonics, enabling the synthesis of metamaterials with engineered optical properties, including refractive index, dispersion, and anisotropy. ...
