The University of Southampton’s world-leading expertise in photonics and fibre optic technology has been awarded the prestigious Queen’s Anniversary Prize(QAP) for Higher and Further Education. Dr Jun-Yu(Bruce) Ou fabricated the QAP logo together with the ORC and the University of Southampton logo on the tip of a sewing needle by focused ion beam technology to celebrate the event. A focused stream of accelerated gallium ions is used as a tool to blast away atoms and molecules so any shape can be carved on the nanometre scale. newslink1 newslink2

The SEM images show the logos of the Optoelectronic Research Centre and the University of Southampton milled on top of a human hair by directly focused ion beam milling. The minimum feature is about 70 nm, 1000 times smaller than the diameter of a human hair!! It is a great example of the power of nanotechnology and has been demonstrated in several outreach events.
