Fig. 5

a, b Stitched confocal optical and FL microscope images of Z-shaped photonic structure constructed from ferroelastic bent 1-Cl crystal waveguides. c, d The stitched confocal optical and FL microscope images of reconfigured Z-shaped structure fabricated from spatially restored 1-Cl crystal waveguides. Insets display the color-coded FESEM images of spatially restored 1-Cl crystals. e, f The emission spectra recorded at various positions on the Z-shaped structure fabricated from bent and spatially restored 1-Cl crystal waveguides, respectively. The blue arrows between (a, c) indicate the mechanical spatial reorientation possible in ferroelastic crystals. In (a, c), the images are presented on light blue colour background panels, for clarity. In (b, d), the images are presented on black background panels, for clarity.
