On-Chip Metamaterial Antenna Array with Distributed Bragg Deflector for Generation of Collimated Steerable Beams
Ginel-Moreno, Pablo; Hadij-El-Houati, Abdelfettah; Sánchez-Postigo, Alejandro; Wanguemert-Pérez, Juan Gonzalo
; Molina-Fernández, Íñigo; Schmid, Jens H.; Cheben, Pavel; Ortega-Moñux, Alejandro[et al.] (WILEY, 2022-07-03)
The generation of collimated steerable beams of light is a fundamental function in optics needed in many applications, including free-space optical communications, remote sensing, and light detection and ranging. Implementing ... -
Polarization insensitive metamaterial engineered multimode interference coupler in a 220 nm silicon-on-insulator platform
Pérez-Armenta, Carlos; Ortega-Moñux, Alejandro; Luque-González, José Manuel; Halir, Robert; Schmid, Jens; Cheben, Pavel; Molina-Fernández, Íñigo; Wanguemert-Pérez, Juan Gonzalo[et al.] (Elsevier, 2023)
High-index contrast silicon waveguides exhibit strong birefringence that hinders the development of polarization-insensitive devices, especially for sub-micrometer silicon layer thickness. Here a polarizationindependent 2 ... -
Simplified colorless characterization scheme for coherent receivers in DWDM scenarios using a single interferer
Reyes-Iglesias, Pedro José; Ortega-Moñux, Alejandro; Izquierdo, D.; Garcés, Ignacio; Molina-Fernández, Íñigo (Elsevier, 2024)
Intradyne coherent receivers, capable of detecting an individual wavelength-division multiplexed channel just by tuning the local oscillator frequency, is of great interest for the development of high-capacity flexible ... -
Tilted subwavelength gratings: controlling anisotropy in metamaterial nanophotonic waveguides
Luque-González, José Manuel; Herrero-Bermello, Alaine; Ortega-Moñux, Alejandro; Molina-Fernández, Íñigo; Halir, Robert; Wang, Shurui; Schmid, Jens H.; Cheben, Pavel; Velasco, Aitor V.[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 ...
