摘要： PROBLEM TO BE SOLVED: To provide an optical wavelength multiplexer/demultiplexer in which low loss and a flat pass region characteristic are realized while a gap width between cores of an input side slab waveguide is made into a width, that is sufficiently buried by a clad material, and without making the pass region into a ripple state. SOLUTION: The optical wavelength is provided with an array waveguide diffraction grating which is made of a plurality of channel waveguides, the input side slab waveguide which is connected to one tip side of the array waveguide diffraction grating, an output side slab waveguide which is connected to other tip side of the array waveguide diffraction grating and an output channel waveguide which is connected to the output side slab waveguide. In the optical wavelength multiplexer/demultiplexer, a Mach-Zehnder circuit is connected to the input side slab waveguide. The width of the waveguide which constitutes of the Mach-Zehnder circuit is formed narrower at the connection section vicinity with the input side slab waveguide. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a star coupler in which transition loss is remarkably reduced, an optical wavelength multiplexer/demultiplexer and an optical device. SOLUTION: In an input side slab waveguide, an input channel waveguide is connected to an input side and an array waveguide diffraction grating, which is constituted of a plurality of array waveguides, is connected to an output side. A clad section forming region 20A is formed to the input side slab waveguide. A plurality of clad sections 21 (21a to 21i are equivalent to one row along a light beam progressing direction), which is made of a core 8 and a clad layer 9, is provided. The clad sections 21 are arranged at the vicinity of the array waveguide diffraction grating and on the extended line of the regions between input ends of the array waveguides and a core height h is gradually made lower as it moves toward a connection section 23. A clad column is constituted of a plurality of the clad sections 21 and a plurality of clad columns is formed in a concentric circular manner. By providing the clad sections 21, transition loss is reduced. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To avoid malfunction of a total reflection type optical switch which uses a nonlinear optical thin film when the optical switch is used under a condition of long-time excitation. SOLUTION: The optical switch makes signal light be obliquely incident on the nonlinear optical thin film 1 containing microcrystal of metal oxide from an optical path 2 provided in an optical medium 3, irradiates the nonlinear optical thin film with visible exciting light, and induces a total reflection phenomenon to control reflection/transmission behavior of the signal light, thereby switching the signal light. The difference in temperature coefficient of a refractive index between the nonlinear optical thin film and the optical medium which comes into contact with the nonlinear optical thin film is set to ≤15×10 -6 /°C. Alternatively, the difference is set preferably to zero or nearly zero. COPYRIGHT: (C)2007,JPO&INPIT
