Abstract

Using new techniques, we fabricated two kinds of piezoelectric films, polyurea-5 and poly-L-lactic acid (PLLA) films, in order to investigate their optical properties, of which the higher order structures are simple. Our main findings are as follows. In the case of the PLLA film fabricated by the new technique, giant optical rotatory power and high-speed light modulation exists. On the other hand, in the case of the polyurea-5 film prepared by vapor deposition polymerization, the Pockels coefficient of 0.09 pm/V is obtained. This value is fairly large for polymers.
