Proceedings ArticleDOI
High performance TM-pass polarizer via subwavelength grating bandgap engineering
Miguel Barona-Ruiz,Carlos Pérez-Armenta,Alejandro Ortega-Moñux,G. Wanguemert-Perez,Íñigo Molina-Fernández,Pavel Cheben,Robert Halir +6 more
TL;DR: In this paper , a low-loss and high-extinction ratio TM-pass polarizer based on tilted subwavelength gratings was proposed to reflect the TE0 mode into the TE1 mode, with a 150 nm bandwidth.
Proceedings ArticleDOI
Silicon Waveguide Photonics for Biosensing Applications
Siegfried Janz,Adam Densmore,D.-X. Xu,Philip Waldron,Jean Lapointe,G. Lopinski,T. Mischki,Pavel Cheben,André Delâge,Boris Lamontagne,Jens H. Schmid +10 more
TL;DR: In this article, the authors present theoretical and experimental results on silicon photonic wire evanescent field (PWEF) sensors that show such PWEF sensors have the highest response to bulk index change as well as surface molecular adsorption.
Proceedings ArticleDOI
SWG dispersion engineering for ultra-broadband photonic devices
Robert Halir,Alejandro Maese-Novo,Sebastian Romero-García,Diego Perez-Galacho,L. Zavargo-Peche,Alejandro Ortega-Moñux,Íñigo Molina-Fernández,J. Gonzalo Wangüemert-Pérez,Pavel Cheben +8 more
TL;DR: In this article, the authors proposed to not only engineer refractive index, but also control SWG dispersion to design ultra-broadband directional couplers with a fivefold bandwidth enhancement compared to conventional devices.
Proceedings ArticleDOI
Dimensionality reduction and optimization for the inverse design of photonic integrated devices
Daniele Melati,Mohsen Kamandar Dezfouli,Yuri Grinberg,Muhammad Al-Digeil,Da Xu,Jens H. Schmid,Pavel Cheben,Abi Waqas,Paolo Manfredi,Shahrzad Khajavi,Winnie N. Ye,P. Nuño-Ruano,Jianhao Zhang,Eric Cassan,Delphine Marris-Morini,Laurent Vivien,Carlos Alonso-Ramos +16 more
TL;DR: In this paper , the authors discuss the potentiality offered by the combination of machine learning dimensionality reduction and multi-objective optimization for the design of high performance photonic integrated devices.
Journal ArticleDOI
Photonic Temperature and Wavelength Metrology by Spectral Pattern Recognition
Siegfried Janz,Ross Cheriton,Dan-Xia Xu,Aadam Densmore,Sergey Dedyulin,A. D. W. Todd,Jens H. Schmid,Pavel Cheben,Martin Vachon,Mohsen Kamandar Dezfouli,Daniele Melati +10 more
TL;DR: In this paper, the spectral pattern recognition is used to measure temperature and generate calibrated wavelength/frequency combs using a single silicon waveguide ring resonator, and two methods of pattern based temperature retrieval are presented.
