Journal ArticleDOI
Non-Invasive On-Chip Light Observation by Contactless Waveguide Conductivity Monitoring
Francesco Morichetti,Stefano Grillanda,Marco Carminati,Giorgio Ferrari,Marco Sampietro,Michael J. Strain,Marc Sorel,Andrea Melloni +7 more
TL;DR: In this article, the authors demonstrate non-invasive light observation in silicon photonics devices by exploiting photon interaction with intra-gap energy states localized at the waveguide surface, where electric contacts are located at a suitable distance from the core, thus introducing no measurable extra-photon absorption.
Journal ArticleDOI
Non-invasive monitoring and control in silicon photonics using CMOS integrated electronics
Stefano Grillanda,Marco Carminati,Francesco Morichetti,Pietro Ciccarella,Andrea Annoni,Giorgio Ferrari,Michael J. Strain,Marc Sorel,Marco Sampietro,Andrea Melloni +9 more
TL;DR: In this article, a non-invasive monitoring and feedback control of high-quality-factor silicon (Si) photonic resonators assisted by a transparent detector that is directly integrated inside the cavity is presented.
Journal ArticleDOI
Photo-induced trimming of chalcogenide-assisted silicon waveguides
Antonio Canciamilla,Francesco Morichetti,Stefano Grillanda,Philippe Velha,Marc Sorel,Vivek Singh,Anu Agarwal,Lionel C. Kimerling,Andrea Melloni +8 more
TL;DR: Results demonstrate that photo-induced treatments can be exploited for a post-fabrication compensation of fabrication tolerances, as well as to set and reconfigure the circuit response.
Journal ArticleDOI
All-optical mode unscrambling on a silicon photonic chip
Francesco Morichetti,Andrea Melloni,Nicola Peserico,Emanuele Guglielmi,Marco Carminati,Marc Sorel,Giorgio Ferrari,Andrea Annoni,Pietro Ciccarella,Stefano Grillanda +9 more
TL;DR: In this paper, a mesh of silicon photonics Mach-Zehnder interferometers is used to self-configure and reset itself after significantly perturbing the mixing, without turning off the beams.
Journal ArticleDOI
Automated Routing and Control of Silicon Photonic Switch Fabrics
Andrea Annoni,Emanuele Guglielmi,Marco Carminati,Stefano Grillanda,Pietro Ciccarella,Giorgio Ferrari,Marc Sorel,Michael J. Strain,Marco Sampietro,Andrea Melloni,Francesco Morichetti +10 more
TL;DR: Automatic reconfiguration and feedback controlled routing is demonstrated in an 8 × 8 silicon photonic switch fabric based on Mach-Zehnder interferometers, making the switch fabric robust against thermal crosstalk, even in the absence of a cooling system for the silicon chip.
