Abstract

We report the appearance of two types of optical stripes with different spatial wavelengths in electroclinic liquid crystals exhibiting a layer deformation. The periodicity of one set of stripes (longer wavelength) scales as twice the thickness of the cell, while the second (shorter wavelength) set of stripes has a periodicity that is independent of the thickness. Finally, detailed data on the spatially resolved optical studies of the stripe texture are presented which suggest the origin of the two types of stripe deformation and provide a possible explanation of their dependence on electric field.
