Editorial Foreword to The ECOC 2022 Special Issue

Niels Quack, Hans Georg Limberger, Rachel Grange, Christian Bosshard

The European Conference on Optical Communications (ECOC) is one of the leading conferences in the field of optical communications and its related topics. The 48th edition took place from 18th-22nd September 2022 in Basel, Switzerland. The conference attrac ...

Monitoring strain gradients in adhesive composite joints by embedded fiber Bragg grating sensors

Véronique Michaud, Hans Georg Limberger, Georgios Violakis, Roohollah Sarfaraz Khabbaz

The adhesive bonding of composite materials can be applied to assemble light-weight structures for aeronautical applications. However, the application of adhesive bonds in primary load-bearing structures is limited by the lack of adequate techniques to mon ...

Stability of Fiber Bragg Gratings Fabricated Using UV Ar+ and ArF Excimer in Bismuth-Aluminum-co-Doped Silica Fibers

Hans Georg Limberger, Georgios Violakis

Continuous annealing of fiber Bragg gratings fabricated using cw and pulsed laser irradiation in Bi-Al-co-doped fibers of different concentrations show activation energy spectra linked to Bi-Al. Thermal stability maps were obtained by their analytical repr ...

Dose dependence of luminescence increase in H2-loaded Bi-Al co-doped optical fibers by cw 244-nm and pulsed 193-nm laser irradiation

Hans Georg Limberger, Georgios Violakis

The near infrared luminescence is increased in H2-loaded Bi-Al co-doped optical fibers by irradiation of cw 244-nm or pulsed 193-nm laser light. The dose dependence is different for the two lasers. ...
