Highly sensitive optical fibre Bragg grating contact pressure sensor embedded in a polymer layer: modelling and experimental validation (2024)
Journal Article

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

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...

Self-consistent simulation of high-brightness diode lasers with external optical feedback (2015)
Conference Proceeding

© 2015 IEEE. This paper presents a model for simulating the impact of external optical feedback on large-optical cavity high-brightness diode lasers. The simulations are performed with our 2.5D simulation tool for high-brightness laser diodes. The ex...

Separate phase-locking and coherent combining of two laser diodes in a Michelson cavity (2015)
Conference Proceeding

We describe a new coherent beam combining architecture based on passive phase-locking of two laser diodes in a Michelson external cavity on their rear facet, and their coherent combination on the front facet. As a proof-of-principle, two ridge lasers... Read More about Separate phase-locking and coherent combining of two laser diodes in a Michelson cavity.

Design Optimisation of High-Brightness Laser Diodes for External Cavity Operation in the BRIDLE Project (2014)
Conference Proceeding

We report on the design aspects of high performance diode lasers for application in high-brightness spectral beam combining and coherent beam combining modules. Key performance trade-offs are identified and potential solutions are explored.

Design and simulation of high-speed nanophotonic electro-optic modulators (2014)
Conference Proceeding

In this work, an ultracompact electro-optic modulator based on refractive index modulation by plasma dispersion effect in PhC all-optical gate (AOG) is proposed. The index modulation is achieved by applying a time-varying bias voltage across the elec... Read More about Design and simulation of high-speed nanophotonic electro-optic modulators.

Factors influencing brightness and beam quality of conventional and distributed Bragg reflector tapered laser diodes in absence of self-heating (2014)
Journal Article

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...
