Photonic crystal fibres (PCFs) – which can ‘cage’ light and small particles – are the theme of a talk tomorrow at 7.30pm at the University’s campus in St Paul Street, Valletta.
Hollow PCFs filled with gases have been used to transform invisible infrared laser pulses into white light, millions of times brighter than any lamp. When filled with small quantities of chemicals they also allow scientists to study chemical processes better.
Other PCFs guide light into an optical vortex, which has fascinating properties. Particles can be optically trapped and forced to travel over 100m inside a PCF, and then used as to measure temperature, vibration, or radiation levels anywhere along the fibre.
The speaker is Prof. Philip Russell, a director of the Max Planck Institute for the Science of Light in Erlangen, Germany.
The talk is organised by Malta Café Scientifique.
The public is invited to attend.
