• Designing polarization management devices by tilting subwavelength grating structures 

      Luque-González, José Manuel; Herrero-Bermello, Alaine; Ortega-Moñux, Alejandro; Molina-Fernández, Íñigo; Velasco, Aitor V.; [et al.] (2019-05-03)
      Subwavelength gratings (SWG) are periodic structures which behave as controllable homogeneous metamaterials. SWGs are extremely interesting when they are used in platforms with a limited choice of material refractive indices, ...
    • Tilted subwavelength gratings: controlling anisotropy in metamaterial nanophotonic waveguides 

      Luque González, J. Manuel; Herrero-Bermello, Alaine; Ortega-Moñux, Alejandro; Molina Fernández, Íñigo; Halir, Robert; [et al.] (2018-10-24)
      Subwavelength grating (SWG) structures are an essential tool in silicon photonics, enabling the synthesis of metamaterials with a controllable refractive index. Here we propose, for the first time to the best of our ...
    • Ultra-broadband Silicon Photonic Multimode Interference Coupler 

      Halir, Robert; Cheben, Pavel; Luque-González, Jose Manuel; Sarmiento-Merenguel, Jose Darío; Schmid, Jens; [et al.] (ECIO, 2017)
      In integrated optics, multimode interference couplers (MMIs) are used as light-wave splitters and combiners in a wide variety of devices ranging from spectrometers to sensors and coherent optical receivers. While their ...
