Re-inventing Multimode Interference Couplers Using Subwavelength Gratings
Ortega-Moñux, Alejandro
; Halir, Robert; Maese-Novo, Alejandro; Alonso-Ramos, C.; Zavargo-Peche, Luis; Pérez-Galacho, Diego; Molina-Fernández, Íñigo; Wanguemert-Pérez, Juan Gonzalo; Cheben, Pavel; Schmid, Jens H.; Lapointe, J.; Xu, Dan-Xia; Janz, Siegfried[et al.] (European Physical Society, IEEE, The Optical Society, 2013)
We use the concept of subwavelength grating (SWG) refractive-index-engineering to propose and experimentally demonstrate a reduced size, slotted 2x2 MMI coupler. We also present an ultra-broadband 2x2 MMI coupler which ... -
Subwavelength Index Engineering for SOI Waveguides
Halir, Robert; Luque-González, José Manuel; Wang, S.; Sarmiento-Merenguel, Jose Darío; Sánchez-Postigo, Alejandro; Wanguemert-Pérez, Juan Gonzalo; Cheben, Pavel; Schmid, Jens H.; Xu, Dan-Xia; Janz, Siegfried; Lapointe, J.; Molina-Fernández, Íñigo; Ortega-Moñux, Alejandro[et al.] (2016-09-06)
Photonic structures with a sub-wavelength pitch, small enough to suppress diffraction, can behave as equivalent homogenous materials that can be engineered to exhibit a specific refractive index and dispersion. Here we ... -
Subwavelength metamaterial engineering for silicon photonics
Halir, Robert; Ortega-Moñux, Alejandro; Soler-Penades, Jordi; Luque-González, José Manuel; Sarmiento-Merenguel, Jose Darío; Sánchez-Postigo, Alejandro; Wanguemert-Pérez, Juan Gonzalo; Schmid, Jens H.; Xu, Dan-Xia; Janz, Siegfried; Lapointe, J.; Molina-Fernández, Íñigo; Nedeljkovic, Milos; Mashanovich, Goran Z.; Cheben, Pavel[et al.] (2017-02-06)
Waveguides structured at the subwavelength scale frustrate di raction and behave as optical metamaterials with controllable refractive index. These structures have found widespread applications in silicon photonics, ranging ...
