Towards new applications using capillary waveguides

Demetri Psaltis, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy

In this paper we demonstrate the enhancement of the sensing capabilities of glass capillaries. We exploit their properties as optical and acoustic waveguides to transform them potentially into high resolution minimally invasive endoscopic devices. We show ...

Analysis of structurally sensitive loss in GaN-based VCSEL cavities and its effect on modal discrimination

Nicolas Grandjean, Gatien Cosendey, Ehsan Hashemi

Lateral loss causes optical energy to leave the laser cavity in the transverse, lateral, direction, and is sometimes neglected to simplify the numerical simulations. However, in contrast to outcoupling and absorption losses, we show that the lateral loss c ...

Single Mode Mid-infrared Waveguide for Evanescent Sensor Scheme in Liquids

Hans Peter Herzig, Vincent Paeder, Lubos Hvozdara, Philip Wägli, Yu-Chi Chang

A Si/Ge based, single mode, mid-infrared optical waveguide, is used as an evanescent sensor in liquid matrix. The selectivity is achieved by the use of quantum cascade lasers (QCLs) tuned to the maximum absorption of a given analyte. The cocaine detection ...
