This chapter describes the potential of liquid crystal (LC) in switching, from LC materials properties and principles to switching parameters and applications, including the advantages and limitations of LC technology in optical switching. A description of the main types of switches based on the mechanisms used for steering the light with LCs such as reflection, waveguide, polarization management or volume beam-steering is summarized with special emphasis on their parameters as switches and their applications. Apart from previous configurations, ...
