Abstract

PURPOSE:To change the threshold of pumping power by biasing a electrode provided in one face of the surface elastic wave transducer. CONSTITUTION:Electrode M1 is provided on the piezo-electric substance surface of the laminated substance consisting of semiconductor S and piezo-electric substance I, and DC bias E1 and AC signal 12 are supplied to electrode M1. Thus, a generated surface wave advances in the horizontal direction. Electrodes M3 and M4 are provided in the left and the right of electrode M1 and are biased. Then, the semiconductor carrier density in this part is changed considerably to change the impedance of the surface wave transmission path considerably. As the result, a reflection wave is generated by electrodes M3 and M4, and energy is accumulated under electrode M1 due to the reflection wave. Thus, pumping power can be reduced by operating the surface elastic wave transducer.
