(a) A reflectance time response of the cell at 715 nm when addressed with a driving voltage of 1000 mV. (b) The calculated characteristic time constants of the optical response. Driving voltages of 600 mV, 800 mV, and 1000 mV are shown in light, medium, a (a) Reflectance ranges achieved when driving the cell with 800 mV. Negative polarity yields a reflectance minimum, whereas positive polarity drives dye out of the crystal for a reflectance maximum. (b) Maximal reflectance variation (λ = 715 nm) (a) Bragg stack photonic crystal microstructure fabricated using GLAD. (b) Schematic representation of assembled cell, not to scale. Reflectance is measured from the top surface.
