It is shown that the Bragg centre-wavelength of a polymeric chiral sculptured thin film (STF) can be shifted by the axial tension generated in a cobonded piezoelectric disc by a DC voltage. This attractive possibility can be exploited for tunable optical filters as well as lasers made of chiral STFs, and can be extended to other types of STFs.
