Monitoring photonic crystal fibre fabrication in real-time
Photonic crystal fibres (PCFs) were first explored in the 1990s, and as conventional optical fibres have revealed their limits, interest in PCFs has only increased further. PCFs use a specific pattern of air-holes which stretch the length of the fibre to guide light. These delicate microstructures are functionally essential, but currently there is no way to monitor their production in […]

The Sun’s crowning glory: observing the corona
How do you observe a faint light next to a very bright one? Put simply, with great difficulty. Our knowledge of the outer atmosphere of the Sun – called its corona – is still fairly limited, due to difficulties observing this part of the Sun. Fortunately, solar eclipses (where the Moon and Sun perfectly overlap ‘in syzygy’) provide scientists, such […]
