A general approach for robust integrated polarization rotators
Alonso-Ramos, C.; Halir, Robert; Ortega-Moñux, Alejandro; Cheben, Pavel; Vivien, Laurent; Molina-Fernández, Íñigo; Marris-Morini, Delphine; Janz, Siegfried; Xu, Dan-Xia; Schmid, Jens H.[et al.] (International Society for Optics and Photonics, 2013)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Polarization management for coherent optical receivers
Halir, Robert; Ortega-Moñux, Alejandro; Pérez-Galacho, Diego; Alonso-Ramos, C.; Ruiyong, Zhang; Reyes-Iglesias, Pedro José; Romero-García, Sebastián; Godoy-Rubio, Rafael; Wanguemert-Pérez, Juan Gonzalo; Molina-Fernández, Íñigo; Runge, Patrick[et al.] (2014-06-03)The constant growth of bandwidth requirements in optical communication networks has prompted the evolution from conventional on-off-keying (OOK) transmission techniques to coherent, polarization multiplexed schemes. The ... -
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 ... -
Robust and tunable integrated polarization rotator
Alonso-Ramos, C.; Halir, Robert; Ortega-Moñux, Alejandro; Cheben, Pavel; Vivien, Laurent; Molina-Fernández, Íñigo; Marris-Morini, Delphine; Janz, Siegfried; Xu, Dan-Xia; Schmid, Jens H.[et al.] (2014-03-11)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Silicon-on-insulator polarization controller with relaxed fabrication tolerances
Sarmiento-Merenguel, Jose Darío; Alonso-Ramos, C.; Halir, Robert; Vivien, Laurent; Cheben, Pavel; Ortega-Moñux, Alejandro; Molina-Fernández, Íñigo; Leroux, X.; Marris-Morini, Delphine; Xu, Dan-Xia; Schmid, Jens H.; Janz, Siegfried[et al.] (2014-07-31)Polarization control is essential in applications ranging from optical communications to interferometric sensors. The implementation of in- tegrated polarization controllers is challenging as they require polariza- tion ... -
Subwavelength metamaterial structures for silicon photonics
Wanguemert-Pérez, Juan Gonzalo; Sánchez-Postigo, Alejandro; Luque-González, José Manuel; Sarmiento-Merenguel, Jose Darío; Halir, Robert; Ortega-Moñux, Alejandro; Molina-Fernández, Íñigo; Soler-Penades, Jordi; Nedeljkovic, Milos; Mashanovich, Goran Z.; Alonso-Ramos, C.; Pérez-Galacho, Diego; González Andrade, David; V. Velasco, Aitor[et al.] (Photonics North, 2017)Sub-wavelength periodic metamaterial structures are enabling the design of silicon photonic devices with unprecedented performance in the near infrared band. However, for applications in the promising mid-infrared band it ...
