Abstract

PURPOSE: To realize a compact and low-loss optical band-stopping filter by providing a transducer for elastic wave excitation at one end of a refractive index distribution type lens.
CONSTITUTION: Projected light from optical fiber 11 strikes refractive-index distribution type lens 12 on which piezoelectric thin-film transducer 13 for elastic wave excitation has been vapor-deposited. On both sides of transducer 13, electrodes 14 of thin metal films are stuck. As an ealstic wave propagates in lens 12, light of specific wavelength is reflected being distributed and no transmitted light is obtained. Light of prescribed wavelength, on the other hand, is focused on the center of the projection flank of lens 12 and led to optical fiber 17. Thus, the band-stopping filter can be obtained.
