Pseudo Ferroelectric Films:
The author has previously obtained a patent of generating these films and the materials. The present paper deals with the possible use of them as the Optical Switches. The white light consisting of the several VIGBYOR frequencies may be used to transmit via exclusively the green light the information on the path of an internet or the intranet using this polymeric film.
The particular film involving the KI material, is easily found dismantled, as a separate entity from the substrate of plastic Petri dish that has been used to prepare this film, and found to give the exclusive green light with the exciting radiation from an ordinary mercury energy saving lamp of 15 watts. The images below show the green optical switch utility of this polymeric pseudo ferroelectric film.
