Orientational light interaction with nematic liquid crystal doped with MEH-PPV polymer
Nonlinear-optical properties of nematic liquid crystal 5CB doped with a small amount of high-molecular polymer MEH-PPV (poly[2-methoxy-5-(20-ethylhexyloxy)1,4-phenylenevinylene]) have been studied. This liquid crystalline system was shown to exhibit a negative nonlinearity due to the light-induced director reorientation away from the light-field direction.
