Fig. 2

a Deformation of a photonic bilayer strip (20 × 2 mm) in response to a green laser (I = 17 m cm−2). b Dependence of maximal displacement on laser intensity. c Dependence of displacement on the laser illumination time (I = 35 m cm−2). d Response rate of bilayers in the initial deformation stage as a function of laser intensity. Inset shows the calculation of response rate, which is defined as the slope of the tangent line. e Dependence of the displacement on the bending cycle number of photonic bilayer film (I = 35 m cm−2). Error bars represent the standard deviation of the measurements (n = 5).
