PRODUCTION OF OPTICAL WAVEGUIDE

摘要: PURPOSE:To enable formation of an optical waveguide which can be connected to multimode fibers as well by forming a ZnO c-axis oriented crystal body on base plate, providing mask formed into the shape thereon and etching in direction. CONSTITUTION:An fiber 11 is input side 20 12, 13 are two output sides 20a, 20b thereof. The light inputted from equally branched branching part advance toward while no voltage impressed between electrodes 22a 22b. When 22b, refractive index distribution arises branch path electric field component direction film right under electrodes. therefore more where higher. More specifically, quantity taken out external changed changing polarity 20b. having cross sectional area large permit connection formed.
