  • Liquid crystal optical frequency shifter
    Patent number: 5739908
    Abstract: An optical frequency shifter is provided to change the frequency of a coherent input light beam by imparting periodic increases in phase to the beam. This increase in phase is caused by ferroelectric liquid crystals (FLCs) in conjunction with quarter wave plates. The FLCs are repeatedly switched on and off by electrical signal generators, adding phase shift in steps, which in turn results in a higher output optical frequency.
