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 Fotónica 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 rotating waveguides with stringent fabrication tolerances. Here, we present a fully integrated polarization controller scheme that signi cantly relaxes the requirements on the rotating waveguides, alleviating fabri- cation tolerances. We analytically establish a technology-independent, easily measurable tolerance condition for the rotating waveguides. Po- larization control in the presence of waveguide width errors of 25% is shown through full vectorial simulation. 2014-07-31T10:19:57Z 2014-07-31T10:19:57Z 2014-07-31 journal article http://hdl.handle.net/10630/7963 eng Group Four Photonics Paris 28 a 30 Mayo de 2014 open access
