Caption

(a) Layout of the optical fibre system used to generate and detect GHz frequency phonons from the tip of a single-mode optical fibre (inset). Scanning the distal end of the ultrasonic probe in space with respect to a microscopic object (inset) allows mapping of elastic (b, overlaid onto brightfield image) and topographic (c) information with high resolution. Scale bars: 10 μm.
