Abstract: The present invention relates to an optical modulator capable of preventing a disconnection of an electrode and improving a discontinuity of a characteristic impedance while realizing a polarization inverting area and a ridge waveguide in a single optical modulator. In the optical modulator, a first electrode is composed of an inverting area electrode portion formed on an upper portion of one of first and second waveguides in the polarization inverting area, a non-inverting area electrode portion formed on an upper portion of the other one of the first and second waveguides in the other area, and a connection portion for making a connection between the inverting area electrode portion and the non-inverting area electrode portion at the boundary between the polarization inverting area and the other area. A supporting mechanism for supporting the connection portion of the first electrode is provided in a groove.

A gate insulation layer is formed on the substrate to cover the patterned first metal layer. A semiconductor layer is formed on the gate insulation layer using a second mask, wherein the semiconductor layer includes an active layer of pure amorphous silicon and an ohmic contact layer of impurity-doped amorphous silicon. A second metal layer is formed on the gate insulation layer to cover the semiconductor layer and then patterned using a third mask to form a data line having a source electrode, a pixel connecting line having a plurality of pixel electrodes, and a drain electrode that is spaced apart from the source electrode. A channel is formed by etching a portion of the ohmic contact layer between the source and drain electrodes. An alignment layer is formed over the substrate to cover the patterned second metal layer. The substrate having the alignment layer and the source and drain electrode is then thermal-treated in a furnace to cure the alignment layer and to anneal a thin film transistor.

Abstract: A method for fabricating titanium-indiffusion waveguides in optical modulators and other optical waveguide devices includes disposing titanium strips in a waveguide pattern on the surface of a crystalline substrate, such as lithium niobate or lithium tantalate, and indiffusing the titanium atoms into the crystalline substrate by pressurizing above ambient atmospheric pressure an oxygen gas atmosphere enclosing the crystalline substrate, heating in the oxygen gas atmosphere, maintaining temperature and pressure for an indiffusion period, and cooling to ambient temperature. A powder formed of the same chemical composition as the crystalline substrate may be introduced into the indiffusion process to limit the crystalline substrate from outgassing alkaline earth metal oxide during the indiffusion period. An indiffusion container that allows for crystalline substrates to be annealed in the presence of a powder without contaminating the substrate with the powder during the indiffusion process may be used. Waveguides manufactured in accordance with the method exhibit superior drift performance.
