Experimental configuration and measurements.
(a) Picture of the PMMA lens. The picture was taken before filling cuvette with index-matching liquid. The lower panel shows a zoomed-in picture of the PMMA lens. Scale bar, 500 μm. (b) Snapshot of representative Brillouin pattern acquired by the camera during measurement. (c) Brillouin spectrum of PMMA. (d) Brillouin spectrum of index-matching liquid. The dots and solid curves are measured data and fitted data, respectively.
