1. A method for forming a light modulating material comprising the steps of:

  • a) forming a solution having a mesogenic component capable of forming a ferroelectric smectic liquid crystal phase and a medium-forming component capable of forming a light transmissive polymer medium;

    b) inducing a force in the solution to promote alignment of molecules of the mesogenic component along a direction relative to a surface of the solution; and

    c) solidifying the medium-forming component while the force is induced to promote phase separation of microdomains of the ferro-electric smectic phase from the polymeric medium.
