a Graphical representation of a twisted crystal. b Confocal optical images of a straight twisted microcrystal of length ≈136 µm and P≈23 µm with its subsequent bent geometries (B1-B4) and respective mechanical strain (ε). Scale bar is 20 μm. c, d FL images of microcrystals on exposure to UV torch in straight and curved (B4) geometries. e The plot of optical loss versus % strain caused due to bending of the crystal waveguide.
