摘要： PROBLEM TO BE SOLVED: To enhance the resistance characteristics of diffracted images to a wavelength deviation and to avert the interference noise by the phase deviation accompanying the wavelength deviation. SOLUTION: A mask 5-4 with openings is arranged between a recording medium 5-2 and a two-dimensional photodetector 5-5. The mask 5-4 has a plurality of apertures 5-6 having regular hexagonal shapes paralleling the straight lines connecting two vertexes furthest from each other of hexagonal shapes to a progressing direction 5-8 of guided light.

摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide having a variety of characteristics and to provide a method for manufacturing the optical waveguide. SOLUTION: The optical waveguide is characterized by the fact that KTax Nb1-x O3 optical functional material is used for the optical waveguide. An optical input signal 3 is transmitted to a KTax Nb1-x O3 film 2. A change in optical property in the KTax Nb1-x O3 film 2 is caused by an external voltage signal applied with an electrode 4. Thus, the transmitted optical signal is modulated by being influenced by the change in the characteristics when the optical signal passes through the KTax Nb1-x O3 film 2. The modulated optical signal is taken out as an optical signal 5.
