Abstract

We have studied the optical nonlinearities of aligned nematic liquid crystalline films in the near IR communication spectral region [1.55 μm]. The measured refractive index coefficients are on the order of 10^-3 cm²/W. The origins of the refractive index changes are thermal indexing effect and director axis reorientation. Phase modulation of several π's can be generated with mW-power near IR lasers in micron thick films.
