摘要
The invention relates to a liquid crystal modulator comprising at least one ferroelectric liquid crystal, and to a method for operating an optical liquid crystal modulator having at least one ferroelectric liquid crystal. The aim of the invention is to greatly diminish temperature-dependent influences during simultaneously short switching times. To this end, the invention provides that the ferroelectric liquid crystals have a DHF mode and an operating range of the electric field that exceeds 10 V/νm at the location of the liquid crystal. The operating frequency is preferably greater than 50 kHz.
