*7.5.1 LC droplet-like morphology*

Generally, this type of morphology has been found in transmission or reflection grating (**Figure 48**). These types of gratings are made up of acrylate- or thiol-enebased monomers. During PIPS process, because of fast curing process (intense curing light and small curing time) and high effective functionality of monomer, LC molecules get diffuse and configure themselves into distinct and elongated LC droplets. These LC droplets, embedded into the polymer matrix, are distinguished in SEM image (**Figure 48(b)**). Here, light scattering is more because the size of the LC droplets is comparable to the wavelength of the visible light [164, 168].
