In this contribution we describe a method of controlling the polarization dependence in holographically formed polymer dispersed liquid crystals using a ferroelectric liquid crystal mixture and a diacrylate monomer. By elevating the temperature of the prepolymer and liquid crystal mixture prior to the holographic exposure, we can control the polymer morphology and therefore the resulting alignment of the ferroelectric liquid crystal. The two distinct polymer morphologies that we manufacture and investigate are droplet and channel like. We investigate these grating structures using optical polarizing microscopy and scanning electron microscopy. We support our polarization dependence results with electro-optic characterization to see if ferroelectrics have added benefits of faster electro-optic response verses nematics in holographically formed polymer dispersed liquid crystal geometries.
