Abstract: A process for fabricating a diffuse reflector includes: mixing a fluid that is immiscible in a solution containing mesogens into the solution to create a mixture containing droplets of the fluid suspended in the mixture; depositing a layer of the mixture on a surface; and processing the layer to form a film in a manner such that the droplets of the fluid disrupt alignment of the reactive mesogens in the solution and nucleate defects that propagate through the film. A diffuse reflector may include a first layer of cholesteric material that reflects a first wavelength of light and fluid droplets distributed in the layer to nucleate defects and separate domains.
