Device and method for the temperature-independent operation of electro-optical switches on the basis of ferroelectric liquid crystals having a deformed helix |
摘要 |
In order to substantially reduce temperature-dependent influences and attendant long switching times in the case of an optical liquid crystal modulator having at least one ferroelectric liquid crystal and in a method for operating an optical liquid crystal modulator, the ferroelectric liquid crystals are provided to have a DHF mode and to exhibit an operating range of an electric field of more than 20 V/mum at the location of the liquid crystal.
