    Two optical signatures of amyloid fibres—luminescence in the blue and a near-infrared signal, which can be observed in in vitro and in vivo tissues—are reported. The findings allow for staining-free characterization of amyloid deposits in human samples and could open the door to innovative diagnostic strategies for neurodegenerative diseases.

    Optical soliton dynamics in large-core hollow capillary fibres is demonstrated. The findings enable the scaling of soliton effects by several orders of magnitude to the multi-millijoule energy and terawatt peak power levels, and open up opportunities for new-generation table-top light sources for ultrafast strong-field physics and advanced spectroscopy.

    It is possible to regulate random lasers by controlling and manipulating their properties, including the number and spatial positions of their lasing modes, and the lasing wavelength and the modal size over wide ranges. Performances comparable with non-random optical cavities with 2D photonic crystals are reported.

    Pre-shaping image wavefronts with random phase to locally reduce Fresnel diffraction to Fourier holography results in Fresnel holograms that form on-axis with full depth control without any crosstalk. This produces large-volume, high-density, dynamic 3D projections with 1,000 simultaneous image planes.
