Abstract: A wavelength converting element having improved wavelength converting efficiency and having a beam shape which facilitates coupling to a fiber or the like, is manufactured at low cost. After a waveguide is formed by carrying out proton exchange at a lower substrate in which inverted domains are formed, an upper substrate is laminated to the lower substrate so as to oppose the waveguide. Thereafter, a heat treatment is carried out and protons diffuse into the upper substrate and the lower substrate such that the waveguide is made to be a waveguide whose refractive index distribution is symmetrical, and simultaneously, the upper substrate and the lower substrate are joined by the heat treatment.

Abstract: A highly efficient channel drop filter. The filter employs a coupling element including a resonator-system between two waveguides, which contains at least two resonant modes. The resonator-system includes one or more interacting resonant cavities which in addition to being coupled to the waveguides, can also be coupled directly among themselves and indirectly among themselves via the waveguides. Each component of the coupling element can be configured or adjusted individually. The geometry and/or dielectric constant/refractive index of the resonator-system are configured so that the frequencies and decay rates of the resonant modes are made to be substantially the same. The filter can achieve 100% signal transfer between the waveguides at certain frequencies, while completely prohibiting signal transfer at other frequencies. In exemplary embodiments, the filter is configured with photonic crystals. In accordance with alternative embodiments of the invention, the filter is configured as an absorption induced on/off switch and modulator. The switching action is achieved with either electrical or optical absorption.

Abstract: In a waveguide type optical device which has an optical waveguide and modulation electrodes for varying its refractive index, both formed in the top of a substrate and a ferroelectric crystal having a pyroelectric effect, the top of the crystal substrate being parallel to the direction of its spontaneous polarization, conductive films are formed in two surfaces of the crystal substrate which cross the direction of the spontaneous polarization. The conductive films are electrically interconnected to thereby prevent a change in the operating temperature characteristic of the optical device which is caused by the pyroelectric effect of the crystal substrate.

Abstract: Disclosed is an integrated optical waveguide. This integrated optical waveguide is obtained by doping a lithium niobate monocrystal simultaneously or in two stages, by a titanium strip, in a manner known per se, to obtain a guiding zone for the optical wave, and by a titanium film of smaller thickness which covers the guiding zone and the lateral zones to preserve a waveguide in the guiding zone and improve the electro-optical behavior of the guide to which an electrical field is applied.

Abstract: A TE-TM mode converter utilizes a Y-cut lithium niobate crystal which includes a straight titanium-diffused channel extending along the Z-axis of the crystal. A parallel pair of electrodes lie symmetrically on opposite sides of the channel. a.c. and d.c. voltage supplies are connected to the electrodes to supply voltages so as to effect complete conversion from one direction of polarization to the other direction of polarization of a wave applied as an input to one end of the channel for abstraction at the opposite end.

Abstract: When an optical waveguide is formed, an area of an opening of a resist mask is equal to an area of a semiconductor layer for a dummy pattern exposed from the resist mask, and the semiconductor layer for the dummy pattern exposed from the resist mask has a uniform thickness in a region in which the dummy pattern is formed. As a result, an effective pattern density does not change in etching the semiconductor layer for the dummy pattern, and accordingly, it is possible to form a rib-shaped optical waveguide having desired dimensions and a desired shape.
