Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into ...

LCD technology utilizes the light-modulating properties of liquid crystals combined with polarizers. These crystals do not emit light directly but use a backlight or reflector to produce images in ...

A micrometer-sized liquid crystal droplet doped with fluorescent dye functions as a nanosecond optical switch that controls light output using light alone. The resonant cavity design cuts the energy ...
