Optical properties of waveguide-coupled nanowires for sub-wavelength detection in microspectrometer applications

In this paper we experimentally investigate optical interactions between gold nanowires and fs-laser written waveguides in a view of applications for stationary-wave integrated Fourier-transform spectrometers in a movable mirror configuration. For this pur ...

On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas

Irène Antoinette Philipoussis, Toralf Scharf, Joab Di Francesco, Maurine Malak Karam Awadallah

We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...

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 ...

Polymer based single mode optical waveguide for spectroscopy applications

Hans Peter Herzig, Irène Antoinette Philipoussis, Toralf Scharf, Maurine Malak Karam Awadallah

In this work, we present for the first time, two dimensional low loss single mode optical waveguides fabricated with EPO materials. The waveguide geometry has a rectangular shape and it is buried between two EPOCLAD layers. Its refractive index distributio ...

Mid infrared waveguide spectroscopy for cocaine detection in liquid environments

Nico de Rooij, Hans Peter Herzig, Peter Van der Wal, Vincent Paeder, Lubos Hvozdara, Philip Wägli, Yu-Chi Chang, Joab Di Francesco

A germanium strip waveguide on a silicon substrate is integrated with a microfluidic chip to detect cocaine in tetrachloroethylene solutions. In the evanescent field of the waveguide, cocaine absorbs the light at 5.8μm, which is emitted from a quantum casc ...

Note: Stacked rings for terahertz wave-guiding

Stefano Alberti, Jean-Philippe Ansermet, Jean-Philippe Hogge, Emile Jacques de Rijk, Alessandro Macor

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the HE11 mode. This simple concept opens the way for ...
