摘要： A waveguide type electro-optical element is made up of a proton-exchanged optical waveguide formed on a substrate which possesses an electro-optical effect. At least one pair of electrodes is formed on the substrate adjacent to the optical waveguide with a buffer layer being disposed between the substrate and the electrodes. A guide beam propagating through the waveguide is diffracted as a result of the application of a voltage to the electrodes. The buffer layer is made of material which has a specific resistance ranging between 10.sup.7 -10.sup.11 .OMEGA.cm. The optical waveguide may be of a form having a split-type optical waveguide consisting of the combination of two Y-shaped waveguides, and a pair of channel optical waveguides constituting a directional coupler.

摘要： A light wavelength converting element which can reduce an amount of light fed-back to a semiconductor laser. The light wavelength converting element converts a wavelength of a fundamental wave which enters from a first end surface side of an optical waveguide to thereby emit a converted wavelength wave from a second end surface side thereof. The second end surface is inclined with respect to the side surface of the optical waveguide. Also provided is a wavelength stabilized laser having a semiconductor laser, a device which feeds a laser beam emitted from the semiconductor laser back to the semiconductor laser, and a band-pass filter. An optical length between the semiconductor laser and the device is made to be longer than a coherent length of the semiconductor laser, thus improving linearity of a current vs. light output characteristic. Further, a light wavelength converting unit and a light wavelength converting module are provided in which, since an LD-SHG unit formed by a semiconductor laser and a light wavelength converting element is hermetically sealed in a package, the LD-SHG unit can be manufactured easily and has excellent stability over time.
