Journal ArticleDOI
Polarization splitting directional coupler using tilted subwavelength gratings.
José Manuel Luque-González,Alaine Herrero-Bermello,Alejandro Ortega-Moñux,Marina Sanchez-Rodriguez,Aitor V. Velasco,Jens H. Schmid,Pavel Cheben,Íñigo Molina-Fernández,Robert Halir +8 more
TL;DR: This work demonstrates polarization splitting with a directional coupler composed of two fully etched subwavelength waveguides, differing only in the tilt angle of the silicon segments.
PatentDOI
Silicon photonic wire waveguide biosensor
TL;DR: In this article, a silicon waveguide sensing element along with a layer of silicon is provided for use in detecting and monitoring molecular interactions, where the sensing element is adjacent to an aqueous solution in which the molecular interactions are occurring.
Proceedings ArticleDOI
Planar waveguide spatial heterodyne spectrometer
Miroslaw Florjanczyk,Miroslaw Florjanczyk,Pavel Cheben,Siegfried Janz,Alan Scott,Brian Solheim,Dan-Xia Xu +6 more
TL;DR: In this paper, a Fourier-transform planar waveguide-based spectrometer was designed and simulated for the near infrared spectral region, where the light spectrum was calculated using discrete spatial Fourier transform of the fringes.
Journal ArticleDOI
Characterization of integrated photonic devices with minimum phase technique
Robert Halir,Íñigo Molina-Fernández,Juan Gonzalo Wanguemert-Perez,Alejandro Ortega-Moñux,Jose De-Oliva-Rubio,Pavel Cheben +5 more
TL;DR: This paper presents a novel method to recover the original device characteristics from the measured power transmission in the presence of curious reflections, which uses minimum phase techniques to reconstruct time domain information which is filtered to remove the reflection artifacts.
Journal ArticleDOI
Photopolymerizable sol-gel nanocomposites for holographic recording
Maria L. Calvo,Pavel Cheben +1 more
TL;DR: In this paper, the authors proposed a new class of volume hologram recording materials, sol-gel nanocomposites, with important advantages for various holographic applications, including data storage.
