The objective of this thesis is to engineer different optical devices based on structuring of the liquid crystals. Initially, we presented various methods to align the liquid crystal molecules and we have detailed the ones which we used during the course of this work. In combination with alignment of liquid crystals we exploited certain physical properties of the liquid crystals to engineer few optical devices. Broadly speaking one can divide these types of devices in three categories viz. Optical filters, spatial modulators and optical waveguides. All three of these devices have an application in telecommunication sector as well as in the other sectors. The structure of cholesteric liquid crystals has a periodic birefringence and gives ris...
