Abstract
Recent studies have shown that most isotropic (liquid phase) liquid crystals ILCs possess large and fast electronic nonlinearities suitable for nanosecond and picosecond switching and limiting operation throughout the entire visible spectrum.1,2 With these ILCs as the wave guiding cores, we have developed thin fiber arrays capable of high quality image transmission and low threshold optical limiting of nanosecond and picosecond laser pulses. Recently, we have succeeded in synthesizing similar nonlinear organic liquids and obtained even better limiting performance.
