Abstract
Polymer dispersed liquid crystal (PDLC) films are made of micron-sized nematic liquid crystal droplets dispersed in a polymer matrix [1]. PDLC films are normally opaque, due to the refractive index mismatch between the liquid crystal and the polymer matrix. However, the opaque state can be switched into a transparent state by applying electric fields [2], or laser heating [3–4]. Recently, second harmonic generation (SHG) by thermosetting PDLC films at their opaque state was reported [5]. The SHG intensity reached a maximum after the PDLC film was fully cured. However, this SHG intensity decreased when a 60 Hz voltage was applied to turn it transparent.
