Ghent University, Applied Physics and Photonics
Optical fiber technology is part of our daily life. Most of our e-mails and website visits are transmitted as a series of very fast light signals through optical fibers, which look like tiny transparent wires. But these fibers are not only used for communication purposes. They can also serve as very efficient sensors, for example to measure pressure down oil boreholes. Whilst these fibers are traditionally made from glass, VUB and UGent join ...
Stochastic modeling of optical buffers and switching system based on Fibre Delay LInes Ghent University
The main objective of the proposed project is the derivation of analytic or semi-analytic solutions for adequate stochastic models of optical buffers and switches, allowing fast and efficient calculation of various performance measures, such as packet loss, mean delay, delay jitter, etc.
Designing affinity-based nanoswitches on a fiber optic surface plasmon resonance biosensor for continuous biomarker monitoring KU Leuven
Throughout the last decades, biomarker monitoring has become standard practice in health care, biotechnology, environmental analysis, and food production among others, as it enables diagnosis, intervention, and quality control. However, this is currently performed via batch measurements, for which samples have to be obtained from the environment of interest, transported to well-equipped laboratories and pretreated, before measurements can be ...
Paradigm shifting optical fiber sensors for axial strain monitoring with silica and polymer photonic crystal fibers Vrije Universiteit Brussel
In this project I will design and develop an optical fiber sensor for temperature-insensitive axial strain measurements and I will improve the repeatability of micro- and nanomachining with femtosecond lasers in silica and polymer photonic crystal fibers (PCFs). My goal is twofold: first I want to overcome the crosssensitivity to temperature of conventional fiber Bragg grating based sensors with a low-cost, integrated microphotonic sensor ...
Carbon nanomaterial enhanced optical fibres for biomedical imaging and sensing (CHARMING). University of Antwerp
Optical fibres are very well-known for their application in telecommunications. In the last decades, they have also become increasingly popular in biomedical applications, where they are used as very sensitive sensors to detect minute amounts of biological cells or as flexible light sources enabling in-vivo microscopy of biological tissue, and as such allow for early diagnosis of medical conditions. At the same time, new so-called 'nanocarbon' ...

Extreme optical nonlinearities in submicron-and nano-dimensioned waveguides (requested equipment: an Optical Parametric Oscillator). Vrije Universiteit Brussel
Over the past several years the research field of nonlinear photonics, that studies the harnessing of light 'with light' regained much attention amongst many research groups worldwide. This renewed interest finds it origin in the development and optimization of special waveguiding structures that allow tailoring the various nonlinear optical processes far better than has ever been before. For this purpose, both photonic crystal fibers and ...
Towards an integrated groundbreaking photonic crystal fiber sensor for reliable measurements of 3-D stretch fields and shear stresses in materials and structures Vrije Universiteit Brussel
In this project we design and develop an optical fiber sensor for temperature-insensitive axial strain measurements and improve the repeatability of micro- and nanomachining with femtosecond lasers in silica and polymer photonic crystal fibers (PCFs). The goal is twofold: first we want to overcome the cross-sensitivity to temperature of conventional fiber Bragg grating based sensors with a low-cost, integrated microphotonic sensor system. To ...
Robust vibration-based damage identification with a novel high-accuracy strain measurement system Vrije Universiteit Brussel
No name available, Francis Berghmans
KU Leuven, Applied Physics and Photonics
Vibration-based damage identification of existing infrastructure currently suffers from the low sensitivity of natural frequencies and modal displacements to certain types of damage while the sensitivity to environmental influences may be sufficiently high to completely mask the effect of severe damage. Modal strains and curvatures are much more sensitive to local damage, but the direct monitoring of these quantities in a dense grid is not ...
FIONA - Fiber sensing Interrogation based on nONlinear dynamics of lAser diodes Vrije Universiteit Brussel
Lasers and optical fibres are part of our daily life: most of our phone calls, e-mails and website visits are transmitted by lasers as a series of very fast light signals through optical fibres. But these components not only serve communication purposes. Optical fibres can also be very efficient sensors, for example to measure strain or temperature. Such sensors are traditionally interrogated by sending well-specified light from a either ...
