Abstract

Nematic liquid crystals (NLCs) are anisotropic molecules which can be oriented to form uniaxial birefringent layers. NLCs aligned between suitably prepared substrates can be used as large aperture retardation plates; furthermore, the retardance of these cells can be tuned by applying an electric field. The ability to vary retardance has numerous applications in polarization control for various optical systems. Liquid crystal devices have evolved to play an important role in laser systems, displays, and optical switches. Theory, construction, performance considerations, and applications of high precision, tunable NLC retardation devices will be discussed.
