TL;DR: In this paper, a Si photonic wire waveguide was incorporated into a Mach-Zehnder interferometer based sensor, configured to monitor the index change of a homogeneous solution.
Journal ArticleDOI
A high-resolution silicon-on-insulator arrayed waveguide grating microspectrometer with sub-micrometer aperture waveguides.
Pavel Cheben,Jens H. Schmid,André Delâge,Adam Densmore,Siegfried Janz,Boris Lamontagne,Jean Lapointe,E. Post,Philip Waldron,Dan-Xia Xu +9 more
TL;DR: A 50-channel high-resolution arrayed waveguide grating microspectrometer with a 0.2 nm channel spacing on a silicon-on-insulator (SOI) platform with high channel density and spectral resolution is demonstrated.
Journal ArticleDOI
Folded cavity SOI microring sensors for high sensitivity and real time measurement of biomolecular binding.
Dan-Xia Xu,Adam Densmore,André Delâge,Philip Waldron,Ross McKinnon,Siegfried Janz,Jean Lapointe,Gregory P. Lopinski,T. Mischki,E. Post,Pavel Cheben,Jens H. Schmid +11 more
TL;DR: It is shown that extending the ring cavity length increases the resonator quality factor, and thereby enhances the sensor resolution and minimum level of detection, while at the same time relaxing the tolerance on the coupling conditions to provide stable and large resonance contrast.
Journal ArticleDOI
Spiral-path high-sensitivity silicon photonic wire molecular sensor with temperature-independent response
Adam Densmore,Dan-Xia Xu,Siegfried Janz,Philip Waldron,T. Mischki,Gregory P. Lopinski,André Delâge,Jean Lapointe,Pavel Cheben,Boris Lamontagne,Jens H. Schmid +10 more
TL;DR: A new silicon photonic wire waveguide evanescent field (PWEF) sensor that exploits the strong evanescence field of the transverse magnetic mode of this high-index-contrast, submicrometer-dimension waveguide is demonstrated with near temperature-independent response.
Journal ArticleDOI
High bandwidth SOI photonic wire ring resonators using MMI couplers.
Dan-Xia Xu,Adam Densmore,Philip Waldron,Jean Lapointe,E. Post,André Delâge,Siegfried Janz,Pavel Cheben,Jens H. Schmid,Boris Lamontagne +9 more
TL;DR: A ring resonator in SOI photonic wire waveguides is demonstrated using a compact MMI coupler with 3mum x 9 mum footprint as the coupling element, and it is demonstrated that these resonators have a wavelength independent Q and extinction ratio over more than 30 nm wavelength range.
