Caption

a, Schematic diagram of the experimental setup. SMF, single-mode fibre. EDFA, erbium-doped fibre amplifier. OSA, optical spectrum analyzer. b, Measured optical transmittance of a 1.1-μm-diameter MNF with a CW waveguided power from 0 to 13 W. c, Optical microscope images showing surface scattering in the same 1.1-μm-diameter MNF with CW waveguided power of 1 W, 5 W and 12 W, respectively. The exposure time is 3 ms in capturing all the three images.
