Abstract

Glassy liquid crystals with identical molecular structures except chirality were synthesized and processed following the same procedure to produce vitrified chiral nematic films with opposite handedness. The anomalies observed in the transmission spectra of single-handed films were attributed to preserved handedness upon reflection from a chiral nematic film and reversed handedness upon reflection from a glass-air interface. The orientation between the directors of the two optical elements comprising a notch filter was found to play a critical role in device performance.
