Engineering the optical properties of silicon using sub-wavelength structures
Halir, Robert
; Ortega-Moñux, Alejandro; Maese-Novo, Alejandro; Perez-Galacho, Diego; Zavargo-Peche, Luis; Molina-Fernandez, Iñigo; Wanguemert-Perez, Juan Gonzalo; Cheben, Pavel; Schmid, Jens H.; Xu, Dan-Xia; Janz, Siegfried; Fedeli, Jean-Marc[et al.] (IEEE Photonics Society, 2013)
In most integrated optics platforms, including silicon-on-insulator, only minor modifications in refractive index are possible. The geometry of the waveguiding structure is thus the only degree of freedom for the design ... -
Polarization management for coherent optical receivers
Halir, Robert; Ortega-Moñux, Alejandro; Perez-Galacho, Diego; Alonso-Ramos, C.; Ruiyong, Zhang; Pedro, Reyes-Iglesias; Sebastián, Romero-García; Rafael, Godoy-Rubio; Gonzalo, Wangüemert-Pérez; Molina-Fernandez, Iñigo; Patrick, Runge[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; Perez-Galacho, Diego; Molina-Fernandez, Iñigo; Wanguemert-Perez, Juan Gonzalo; Cheben, Pavel; Schmid, Jens H.; Lapointe, J.; Xu, D.; 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 gratings for sensing and polarization management
Wanguemert-Perez, Juan Gonzalo; Cheben, Pavel; Ortega-Moñux, Alejandro; Perez-Galacho, Diego; Alonso-Ramos, C.; Halir, Robert; Molina-Fernandez, Iñigo; Xu, D .-X.; Schmid, Jens H.[et al.] (2014-05-12)
Sub-wavelength grating (SWGs) structures are becoming important building blocks in planar waveguide photonic devices [1]. SWG structures have been successfully applied in the design of a range of devices with remarkable ... -
Subwavelength metamaterial structures for silicon photonics
Wanguemert-Perez, Juan Gonzalo; Sanchez-Postigo, Alejandro; Luque-González, José Manuel; Sarmiento-Merenguel, Jose Darío; Halir, Robert; Ortega-Moñux, Alejandro; Molina-Fernandez, Iñigo; Soler-Penades, Jordi; Nedeljkovic, M.; Mashanovich, G.Z.; Alonso-Ramos, C.; Perez-Galacho, Diego; González Andrade, D.; 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 ...
