FIG. 1.

Bragg peak reflectance for a sintered polystyrene opal (dotted curve), large-pore inverse opal (dashed curve), and LC infiltrated inverse opal (solid curve). The Bragg peak of the LC infiltrated sample was centered at with a FWHM of .

FIG. 2.

(Color online) Dependence of reflectance on applied field for low and high frequency bias. (a) Bragg peak tuning with increasing electric field amplitude for a square wave. (b) Bragg peak tuning for the same amplitudes applied at . (Both data sets displayed hysteresis when the electric field was removed.)

FIG. 3.

(Color online) Spectral dependence of Bragg reflectance for no applied field (black-solid curve) at (blue dotted) and (red dashed) for square-wave electric field amplitude of . Blue and red Bragg peak shifts yield an overall shift of .
