英文摘要 | PURPOSE:To control the effective refractive index of an optical waveguide variably by applying voltage to the side section of the optical waveguide and changing a refractive index between the region of the inside of the optical guide and the region of a side section thereof. CONSTITUTION:Since the refractive indices of a waveguide layer 3 and clad layers 2, 4 on both sides of the layer 3 differ, light beams are propagated along the waveguide layer 3, and the bands of sections on both sides of the waveguide layer are bent when voltage is applied between an electrode 6 and an electrode 7, and an effective band gap changes. Consequently, the absorption coefficient of the region alters, a refractive index varies, and refractive index difference is formed among the central section and the sections on both sides of the waveguide layer 3. That is, the change of refractive indices is generated on the waveguide layer 3 and the side sections of the clad layers 2, 4 by applying voltage to the electrodes 6, 7, and regions 8 in which the change of refractive indices is generated substantially coincide with regions in which bands are bent by applying voltage, thus variably controlling a position where refractive index difference is generated in an optical guide and the variation of the refractive index. |
