Webinar on
Advanced
laser processing of high-performance photonic sensors
Calum
Ross, Heriot Watt University
5th
March 2026 at 3pm (UK time)
Fibre optic sensors are
used widely across many industries, from chemical processing to healthcare.
These sensors often rely on intricate optical systems at the sensing tip that
are challenging to manufacture due to precise alignment and assembly processes.
A laser-based manufacturing technique has emerged as an ideal tool for
manufacturing complex fibre optic sensors: selective laser etching (SLE).
SLE is a two-step direct laser writing and chemical etching technique
compatible with several transparent materials, including fused silica. SLE
offers truly 3D machining of glass with micron-scale feature resolution and up
to cm-scale part size.
In this webinar, I will
discuss some of the benefits of SLE and present our recent work towards
overcoming key challenges associated with it. I will present a series of glass
sensors manufactured by SLE, including a compact and low-cost fibre-optic Raman
probe developed for optical biopsy applications.
This webinar will last no longer than
one hour.
The webinar is for CPACT members only.
