Abstract: A method of fabricating a voltage-tunable liquid crystal-based notch filter requires filling at least two LC cells with cholesteric LC material to create LH and RH LC cells while applying heat to the cell substrates such that their temperatures are raised to near, but below, the clearing point, such that the LC material remains in the cholesteric state. An AC voltage is applied and turned off repeatedly while the LC cells cool down to room temperature, to cause the LC molecules to temporarily deviate from their intrinsic helical alignment. The cells are passed under a UV light sufficient to create cross-linked polymer networks, and self-compensation is used to compensate for in-band retardation. The resulting LH and RH LC cells are stacked such that the electrodes on adjacent substrates are connected to form a common electrode.
