摘要： PROBLEM TO BE SOLVED: To provide a wavelength branching filter circuit suitable for high integration by achieving the reduction of a size and improving element characteristics such as acceleration and transmission efficiency, and performance. SOLUTION: A waveguide is not individually formed like a conventional arrayed waveguide grating, a material having a different refractive index is periodically arrayed. Thereby, intense wavelength dispersion characteristic which is not showed in a normal optical crystal, is created to control a wavelength deflection. Both sides of a substrate 1 having a structure in which atomic media 5 are embedded in a background medium 4 in a two-dimensionally triangular disposition, are held by a first clad 2 and a second clad 3. The incident plane 6 of an optical signal is inclined at a constant angle to an incident direction, and the signal is outputted from a light-emitting plane 7. The adjacent space of the atomic media 5 is designed according to the wavelength of the optical signal, and the thickness of the substrate 1 is designed so that the optical signal is sufficiently shut into the substrate 1 and a light traveling direction does not deviate largely from a substrate surface.
