Abstract
We describe methods and devices for manipulating optical signals. A method of manipulating an optical signal comprises providing a device () comprising a layer () of blue phase liquid crystal in the path of the optical signal; and applying a dynamically varying spatial pattern of voltages across the layer () of blue phase liquid crystal, thereby causing the refractive index of the layer () of blue phase liquid crystal to vary according the dynamically varying spatial pattern.
