Fig. 3 Mechano-optical devices based on 2D CTO DUV hydrogel.

Caption

a A photo of the CTO hydrogel (left) and scheme (right) of its fabrication process. b Compressive stress–strain curves of the CTO hydrogel. c Phase retardation induced by the uniaxial compression of hydrogel in the direction of light propagation. d Cycling test for the reversibility and stability of DUV modulation during compression. e-g Similar to b-d, but presenting the process of stretching.
