Excitation of Metallic Nano-Cavities by a Silicon Waveguide for Localized Sensing Applications

Hans Peter Herzig, Gaël David Osowiecki, Vincent Paeder, Ali Naqavi, Qing Tan, Armando Cosentino

Strong Electric-field enhancement in small volumes is the key for label-free single-molecule sensing. We have investigated the excitation of single and multiple metallic nano-cavities by evanescent wave coupling in the near-infrared by a silicon wire waveg ...

Combining Visible and Near-Infrared Cues for Image Categorisation

Neda Salamati

Standard digital cameras are sensitive to radiation in the near-infrared domain, but this additional cue is in general discarded. In this paper, we consider the scene categorisation problem in the context of images where both standard visible RGB channels ...

3D Near-infrared Imaging based on a Single-photon Avalanche Diode Array Sensor

Matthias Wolf, Edoardo Charbon, Cristiano Niclass, Claudio Favi, Juan Mata Pavia

A new imager for 3D near-infrared imaging has been designed based on a single-photon avalanche diode (SPAD) imager with 128x128 pixels capable of performing time-resolved measurements with a resolution of 97ps. The imager linearity has been improved to mak ...

Thesis plan proposal February 2011

Aleksandra Zabuga

The research proposal describes the spectroscopic technique to study the intermediate state of protonated peptides formed after the UV excitation. It was shown previously that with the assistance of the CO2 laser the side chain loss fragmentation was enhan ...

Theoretical and experimental study of a 30nm metallic slot array

Hans Peter Herzig, Qing Tan, Armando Cosentino

We present the simulation, fabrication, and characterization of a metallic slot grating on a silicon waveguide (30nm slot width for a period of 500nm). According to the simulation, the experimental measured spectrum of the structure exhibits a dip in the n ...

10Gbps Parametric Short-Wave Infrared Transmitter

Camille Sophie Brès

We demonstrate the first 10Gb/s parametric transmitter in short-wave Infrared band. The device operates by converting 1278nm signal over 85THz to generate channel at 2002nm using highly-nonlinear-fiber and was characterized by error-free performance. ...

Multispectral SIFT for Scene Category Recognition

Sabine Süsstrunk, Matthew Brown

We use a simple modification to a conventional SLR camera to capture images of several hundred scenes in colour (RGB) and near-infrared (NIR). We show that the addition of near-infrared information leads to significantly improved performance in a scene-rec ...

Correlation-based Joint Acquisition and Demosaicing of Visible and Near-Infrared Images

Sabine Süsstrunk, Yue Lu, Zahra Sadeghipoor Kermani

Joint processing of visible (RGB) and near-infrared (NIR) images has recently found some appealing applications, which make joint capturing a pair of visible and NIR images an important problem. In this paper, we propose a new method to design color filter ...

Palm Vein Recognition with Local Binary Patterns and Local Derivative Patterns

Leila Mirmohamadsadeghi, Andrzej Drygajlo

Palm vein feature extraction from near infrared images is a challenging problem in hand pattern recognition. In this paper, a promising new approach based on local texture patterns is proposed. First, operators and histograms of multi-scale Local Binary Pa ...

Multispectral Interest Points for RGB-NIR Image Registration

Sabine Süsstrunk, Matthew Brown, Damien Firmenich

This paper explores the use of joint colour and near-infrared (NIR) information for feature based matching and image registration. In particular, we investigate multispectral generalisations of two popular interest point detectors (Harris and difference of ...
