• Curved waveguide grating demultiplexer (CWG) with a flattened response via bimodal output waveguides 

      Hadij ElHouati, Abdel; Halir, Robert; Ortega-Moñux, Alejandro; Wanguemert-Perez, Juan Gonzalo; Schmid, J.H.; [et al.] (2022-05-08)
      We demonstrate a compact wavelength demultiplexer for the silicon-on-insulator platform based on the curved waveguide grating (CWG) architecture. The proposed device uses bi- modal output waveguides to achieve a low-loss ...
    • Design of subwavelength grating metamaterial waveguides for communications and sensing applications 

      Ortega-Moñux, Alejandro; Luque-González, José Manuel; Pereira Martín, Daniel; Sánchez Postigo, Alejandro; Hadij ElHouati, Abdel; [et al.] (2019-07-04)
      In this work we will cover some of our recent advances in the design of state-of-the-art silicon photonic devices based on all-dielectric subwavelength grating (SWG) metamaterials. Specifically, we will focus on the design ...
    • Low-loss curved waveguide grating wavelength demultiplexer 

      Hadij ElHouati, Abdel; Ortega-Moñux, Alejandro; Wanguemert-Perez, Juan Gonzalo; Halir, Robert; Wang, Shurui; [et al.] (2021)
      We demonstrate a compact wavelength demultiplexer for the silicon on insulator platform based on the curved waveguide grating (CWG) architecture. We mitigate off-chip radiation loss by enforcing the single beam condition ...
