Transmittance and reflectance of an imprinted cholesteric elastomer during a segregation process

We have calculated the reflectance and transmittance of obliquely incident circularly polarized light on a distorted cholesteric elastomer slab distorted. The distortion is achieved by variations of the chiral order parameter, which is defined as the imprinting efficiency of the volume fraction of t...

Sumario:We have calculated the reflectance and transmittance of obliquely incident circularly polarized light on a distorted cholesteric elastomer slab distorted. The distortion is achieved by variations of the chiral order parameter, which is defined as the imprinting efficiency of the volume fraction of the absorbed molecules from the racemic solvent, having the preferably absorbed chirality. We have found a right-handed band reflection whose bandwidth increases and blue-shifts as incidence angle increases. A thinner left-handed band reflection also is observed. The slab be used in a chemically controlled optical filter or optically traced chiral pump.
