Polarization-altering properties of a unique photoinduced chiral material, which consists of a photoresponsive azobenzene (PCDY50), are investigated in detail under an ellipsometric analysis based on a circular basis. The validity of the processes is confirmed by comparing experimental results and calculations. Furthermore, various kinds of optical functions, such as an optical rotator and ellipticity modificator, are demonstrated by applying invariant ellipticity (or azimuth) state condition to the PCDY50 thin film that is less than 1   μm thick.
