Annular focusing by a GRIN lens
Main Author: Jason Guenette Organization: Université Laval, Canada Generally to produce a tight annular beam, we use a lens-axicon doublet. Axicons are difficult to produce and may lead to inconsistent results. To overcome this limitation, we have explored de possibility to produce an annular beam using graded index material. We propose to use a GRIN lens with a custom refractive index profile which is built from an MCVD fiber preform. Using CodeV simulation tools, we show different index profile and raytracing to demonstrate the feasibility. We show that the width of the ring produce by this GRIN is diffraction limited as it is the case for lens axicon doublet. |

Bloch surface wave based biosensing
Main Author: Norbert Danz Organization: Fraunhofer IOF Jena, Germany An integrated biosensing platform exploiting the properties of Bloch surface waves on all-dielectric thin film stacks is described. It combines label-free sensing based on angular resonance tracking with surface wave enhanced fluorescence excitation and detection. Detailed design considerations reveal a system with defined attenuation to improve resolution limits in both modes. |

Uncertainty-Aware Design of Photonic Devices
Main Author: Daniele Melati Organization: National Research Council of Canada, Canada Uncertainty and non-idealities are ubiquitous in the fabrication of photonic devices and circuits. The availability of efficient techniques to evaluate their impact on the device performance allows to include uncertainty directly into the design flow, exploit optimization tools, improve tolerance robustness and ultimately increase fabrication yield. |
