Journal ArticleDOI
Guiding and confining light in void nanostructure.
TL;DR: It is shown that by use of a novel waveguide geometry the field can be confined in a 50-nm-wide low-index region with a normalized intensity of 20 microm(-2), approximately 20 times higher than what can be achieved in SiO2 with conventional rectangular waveguides.
Journal ArticleDOI
All-optical control of light on a silicon chip
TL;DR: The experimental demonstration of fast all-optical switching on silicon using highly light-confining structures to enhance the sensitivity of light to small changes in refractive index and confirm the recent theoretical prediction of efficient optical switching in silicon using resonant structures.
Journal ArticleDOI
Slot-waveguide biochemical sensor
Carlos Angulo Barrios,Kristinn B. Gylfason,Benito Sanchez,Amadeu Griol,Hans Sohlström,Miquel Holgado,R. Casquel +6 more
TL;DR: An experimental demonstration of an integrated biochemical sensor based on a slot-waveguide microring resonator that detects a minimal refractive index variation of 2x10(-4) RIU.
Journal ArticleDOI
A packaged optical slot-waveguide ring resonator sensor array for multiplex label-free assays in labs-on-chips
Carl Fredrik Carlborg,Kristinn B. Gylfason,Andrzej Kaźmierczak,Fabian Dortu,M. J. Banuls Polo,A. Maquieira Catala,G. M. Kresbach,Hans Sohlström,T. Moh,Laurent Vivien,J. Popplewell,G. Ronan,Carlos Angulo Barrios,Göran Stemme,W. van der Wijngaart +14 more
TL;DR: The design, fabrication, and characterisation of an array of optical slot-waveguide ring resonator sensors, integrated with microfluidic sample handling in a compact cartridge, for multiplexed real-time label-free biosensing is presented.
Journal ArticleDOI
All-optical switching on a silicon chip.
Vilson R. Almeida,Carlos Angulo Barrios,Roberto R. Panepucci,Michal Lipson,Mark A. Foster,Dimitre G. Ouzounov,Alexander L. Gaeta +6 more
TL;DR: An experimental demonstration of fast all-optical switching on a silicon photonic integrated device by employing a strong light-confinement structure to enhance sensitivity to small changes in the refractive index.
