The Role

Responsibilities

• Undertake experimental work to optimise laser transmission through optical fibres for use in a downhole assembly
• Help develop and verify models and fibre metrology approaches to characterise high-power fibre performance
• Work hands-on in the lab with high-power fibre optics (CW, 100 W+), free-space optical components, and hollow-core / photonic crystal fibres
• Couple laser sources into optical fibres and optimise coupling efficiency
• Run Zemax / FEM simulations of high-power fibre propagation to support design and troubleshooting
• Collaborate closely with other engineering teams within the company to integrate fibre subsystems into the full prototype device
