Abstract
Liquid crystals [LCs] in their various ordered and disordered phases have been shown to possess large optical and electro-optical nonlinearities over wide temporal [cw to picosecond] and spectral [visible to infrared] ranges. This paper, presents recently obtained image transmission results of liquid crystal (LC) fiber arrays and analytical modelling results of the observed nonlinear propagation of nanosecond laser pulses. Several nonlinear optical processes could occur when a laser pulse is incident on the liquid crystal array. Self-defocusing and bubble formation within the focused laser's confocal region at the entrance and exit planes, nonlinear absorption and subsequent temperature and density changes and nonlinear scattering, guided-mode extinction within the fiber core, could all act to limit the transmission above some intensity/fluence levels.
