Wanguemert-Perez, Juan Gonzalo
; Pérez-Armenta, Carlos; Ginel-Moreno, Pablo; Luque-González, José Manuel; Hadij-El-Houati, Abdelfettah; Sanchez-Postigo, Alejandro; De-Oliva-Rubio, Jose; Ortega-Moñux, Alejandro; Halir, Robert; Schmid, Jens H.; Cheben, Pavel; Molina-Fernandez, Iñigo[et al.] (SPIE, 2023-02)
We present two novel topologies of subwavelength grating (SWG) waveguides: the bricked-SWG and the evanescently-coupled-SWG. The bricked topology enables accurate control of waveguide anisotropy while maintaining the index ... -
Butler Matrix Based Six-port Passive Junction
Moscoso Mártir, Álvaro; Ávila Ruiz, Jose Manuel; Durán Valdeiglesias, Elena; Moreno-Pozas, Laureano; Molina-Fernandez, Iñigo; Ortega-Moñux, Alejandro; De-Oliva-Rubio, Jose[et al.] (2014-02-03)
In this work we propose the utilization of the Butler matrix as a six-port I/Q demodulator. The inherent symmetry of its topology allows to overcome the intrinsic amplitude and phase imbalances of the traditional approaches ... -
