Cut-away of hollow core photonic bandgap fiber, generated by fluid dynamics simulation.
Cut-away of a hollow core photonic bandgap fiber, as generated by a fluid dynamics simulation. The ~1cm wide preform is drawn down to a slender ~0.2mm fibre in a hot furnace under gravity and longitudinal tension. The outer glass is coloured to show temperature (hottest region in white), while the microstructure is coloured to show whether surface tension (blue) or differential pressure (red) forces dominate.
