Abstract :
We propose an optical multi-transmission system using a pyroelectric and optical piezoelectric element as transmitter. We apply the PLZT element to the proposed system as the pyroelectric and optical piezoelectric element. The PLZT element generates the electric charge according to the change of temperature and strength of the UV irradiation. We aim at an energy supply system using the pyroelectric effect, and an information transmission system using the optical piezoelectric effect. We show a numerical model of the transmission system using the PLZT element and simulation results of the transmission of the photo energy and information source to the electric information. The experimental results explain the performance of the developed transmission system and its capability
