Ginel-Moreno, Pablo; Sánchez-Postigo, Alejandro; De-Oliva-Rubio, Jose
; Hadij-El-Houati, Abdelfettah; Ye, Winnie N.; Wanguemert-Pérez, Juan Gonzalo; Molina-Fernández, Íñigo; Schmid, Jens H.; Cheben, Pavel; Ortega-Moñux, Alejandro[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 ... -
Metamaterial antenna array fed by distributed Bragg deflector for beam steering on SOI platform
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.] (2023)
The capability to radiate collimated steerable beams of light is crucial for many applications, such as remote sensing and free-space optical communications. Here we experimentally demonstrate a novel 1D-antenna array ... -
Metamaterial antenna array fed by distributed Bragg deflector for SOI platform
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.] (2022)
We propose a distributed Bragg deflector working as a low loss (<0.3 dB) ultra compact beam expander, which generates an on chip Gaussian beam that illuminates a 1D array of 112 optical antennas with a length of 1.5 mm . ... -
Subwavelength-engineered metamaterial devices for integrated photonics
Sánchez-Postigo, Alejandro; Ginel-Moreno, Pablo; Pereira-Martín, Daniel; Hadij-El-Houati, Abdelfettah; Luque-González, José Manuel; Pérez-Armenta, Carlos; Wanguemert-Pérez, Juan Gonzalo; Ortega-Moñux, Alejandro; Halir, Robert; Schmid, Jens H.; Soler-Penades, Jordi; Nedeljkovic, Milos; Ye, Winnie N.; Mashanovich, Goran Z.; Cheben, Pavel; Molina-Fernández, Íñigo[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-Pérez, Juan Gonzalo; Ortega-Moñux, Alejandro; Halir, Robert; Pereira-Martín, Daniel; Luque-González, José Manuel; Schmid, Jens H.; Wang, Shurui; Vachon, Martin; Xu, Dan-Xia; Soler-Penades, Jordi; Nedeljkovic, Milos; Mashanovich, Goran Z.; Cheben, Pavel; Molina-Fernández, Íñigo[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. ... -
Ultra-broadband polarization beam splitter with a gradual anisotropy engineered subwavelength metamaterial
Luque-González, José Manuel; Halir, Robert; Wanguemert-Pérez, Juan Gonzalo; Schmid, Jens H.; Cheben, Pavel; Molina-Fernández, Íñigo; 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 ...
