Highly sensitive optical fibre Bragg grating contact pressure sensor embedded in a polymer layer: modelling and experimental validation. Results in Optics, 14, Article 100604. https://doi.org/10.1016/j.rio.2024.100604

This paper discusses mathematical modelling and experimental validation of a highly sensitive optical fibre Bragg grating (FBG) contact pressure sensor developed for healthcare applications. Bare FBGs are not very sensitive to pressure (~ 3x10-3 nm/M...

High-power operation of coherently coupled tapered laser diodes in an external cavity (2016)
Journal Article
Schimmel, G., Doyen, I., Janicot, S., Hanna, M., Georges, P., Lucas-Leclin, G., …Traub, M. (2016). High-power operation of coherently coupled tapered laser diodes in an external cavity. Proceedings of SPIE, 9733, Article 97330I. https://doi.org/10.1117/12.2211613

We demonstrate a rear-side phase-locking architecture with two high-brightness diode lasers. This technique is based on the passive phase-locking of emitters in an external cavity on their rear facet, and their coherent combination on the front facet...

Factors influencing brightness and beam quality of conventional and distributed Bragg reflector tapered laser diodes in absence of self-heating (2014)
Journal Article
Kaunga-Nyirenda, S. N., Bull, S., Lim, J. J., Hasler, K., Fricke, J., & Larkins, E. C. (2014). Factors influencing brightness and beam quality of conventional and distributed Bragg reflector tapered laser diodes in absence of self-heating. IET Optoelectronics, 8(2), https://doi.org/10.1049/iet-opt.2013.0082

In this study, the authors examine some of the factors affecting the brightness and the beam quality of high-power tapered lasers. The large volume resonators required to achieve a high-power, high-brightness operation make the beam quality sensitive...
