    • The present invention provides a polarized light mode converter which can be provided within a two-dimensional photonic crystal or can be smoothly connected to a two-dimensional photonic crystal. In a two-dimensional photonic crystal made of a slab-like main body provided with a plurality of different refractive index regions (for example, holes 22) arranged in a lattice in the main body, where the different refractive index regions have a refractive index different from that of the main body, a polarized light conversion waveguide 23 is formed which is comprised of defects of the different refractive index regions arranged linearly whose a cross-sectional shape is asymmetrical in a vertical and in a horizontal direction. The polarized light conversion waveguide 23 can be, for example, realized by providing, on a side of the waveguide, holes 221 and 222 extending in a direction oblique to a the main body surface. TE polarized light propagating through the polarized light conversion waveguide 23 is partially converted into TM polarized light due to the asymmetry of the cross-sectional shape of the waveguide. Since the polarized light mode converter is made of a two-dimensional photonic crystal, it can be provided within a two-dimensional photonic crystal or can be smoothly connected to a two-dimensional photonic crystal.
    • 本发明提供一种可以设置在二维光子晶体内或者可以平滑地连接到二维光子晶体的偏振光模式转换器。 在由板状主体构成的二维光子晶体中,其具有在主体中以格子排列的多个不同的折射率区域(例如,孔22),其中不同的折射率区域具有折射率 与主体不同的是,形成偏振光转换波导23,该偏振光转换波导23由横截面形状在垂直方向和水平方向上不对称的直线布置的不同折射率区域的缺陷构成。 例如,偏振光转换波导23可以通过在波导侧设置沿着与主体表面倾斜的方向延伸的孔221和222来实现。 由于波导的横截面形状的不对称性,通过偏振光转换波导23传播的TE偏振光被部分地转换为TM偏振光。 由于偏振光模式转换器由二维光子晶体制成,所以它可以设置在二维光子晶体内,或者可以平滑地连接到二维光子晶体。

    • The invention provides a substrate for a display which can be easily repaired even when there are problems such as inter-layer shorting attributable to invasion of static electricity. The substrate has a first wiring section disposed in a display area thereof and formed so as to outwardly extend from the inside of the display area. The substrate also has a second wiring section formed such that it intersects the first wiring section outside the display area on the substrate with an insulation film interposed between them. The substrate further has an opening formed in the second wiring section at least in a region thereof overlapping the first wiring section intersecting the same. Further, the substrate has overlapping portions formed at two ends of the opening where the first and second wiring sections overlap each other with the insulation film interposed between them.

    • The present invention is aimed at providing a two-dimensional photonic crystal wavelength multiplexer/demultiplexer capable of multiplexing and demultiplexing both TE and TM-polarized lights. In the wavelength multiplexer/demultiplexer, first and second resonators having the same resonance wavelength λr are provided between first and second waveguides and which are separately provided in a two-dimensional photonic crystal having a photonic band gap for the TE polarization. A first polarization converter for converting a TM-polarized light to a TE-polarized light is provided on the first waveguide 121 between the first and second resonators and. Similarly, a second polarization converter for converting a TE-polarized light to a TM-polarized light is provided on the second waveguide between the first and second resonators and. Among the light propagating through the first waveguide, the TE-polarized light with wavelength λr is introduced from the first resonator into the second waveguide, whereas the TM-polarized light is converted to a TE-polarized light by the first polarization converter and then introduced through the second resonator into the second waveguide.
