Luque-González, José Manuel; Herrero-Bermello, Alaine; Ortega-Moñux, Alejandro
; Sánchez-Rodriguez, Marina; Velasco, Aitor V.; Schmid, Jens H.; Cheven, Pavel; Molina-Fernandez, Iñigo; Halir, Robert[et al.] (2020-12-03)
Tilted subwavelength gratings (SWG) allows anisotropy tailorable metamaterials with applications in polarization management. Based on this concept, here we experimentally demonstrate a broadband directional-couplerbased ... -
Designing polarization management devices by tilting subwavelength grating structures
Luque-González, José Manuel; Herrero-Bermello, Alaine; Ortega-Moñux, Alejandro; Molina-Fernandez, Iñigo; Velasco, Aitor V.; Cheben, Pavel; Schmid, Jens H.; Wang, Shurui; Halir, Robert[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, ... -
Metamaterial engineered C+L band 90º hybrid with 150 nm feature size
Hadij-El-Houati, Abdelfettah; Halir, Robert; Ortega-Moñux, Alejandro; Wanguemert-Perez, Juan Gonzalo; Podmore, Hugh; Schmid, Jens H.; Cheben, Pavel; Molina-Fernandez, Iñigo[et al.] (2020-09-28)
90º hybrids are important components for coherent optical communications. Conventional implementations only cover the C band, while broadband, metamaterial-based devices require sub-100nm feature sizes. We propose a ... -
Polarization-insensitive multimode interference coupler based on bricked subwavelength gratings
Pérez-Armenta, Carlos; Ortega-Moñux, Alejandro; Luque-González, José Manuel; Halir, Robert; Reyes Iglesias, Pedro José; Schmid, Jens H.; Cheben, Pavel; Molina Fernandez, Íñigo; Wanguemert-Perez, Juan Gonzalo[et al.] (2022)
The recently proposed bricked patterning enables enhanced performance in integrated photonics devices based on subwavelength gratings, including polarization insensitivity. We report on the design of a polarization-agnostic ... -
Subwavelength-engineered metamaterial devices for integrated photonics
Sánchez-Postigo, Alejandro; Ginel-Moreno, Pablo; Pereira-Martín, Daniel; Hadij-ElHouati, Abdelfettah; Luque-González, José Manuel; Pérez-Armenta, Carlos; Wanguemert-Perez, Juan Gonzalo; Ortega-Moñux, Alejandro; Halir, Robert; Schmid, Jens H.; Soler-Penades, Jordi; Nedeljkovic, Milos; Ye, Winnie N.; Mashanovich, Goran Z.; Cheben, Pavel; Molina-Fernandez, Iñigo[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 ... -
Ultra-broadband polarization beam splitter with a gradual anisotropy engineered subwavelength metamaterial
Luque-González, José Manuel; Halir, Robert; Wanguemert-Perez, Juan Gonzalo; Schmid, Jens H.; Cheben, Pavel; Molina-Fernandez, Iñigo; Ortega-Moñux, Alejandro[et al.] (2022-06)
In this work we propose a polarization beam splitter based on an advanced SWG metamaterial topology which controls the propagation of multiple TE and TM modes at the same time. The proposed device achieves a simulated ...
