    摘要： Provided is an optical isolator using a photonic crystal. The optical isolator includes an input portion (50) including an input waveguide part (54) formed of the photonic crystal and an input waveguide (55) having a taper portion (52) formed in the input waveguide part. An output portion (70) includes an output waveguide part (74) formed of the photonic crystal and an output waveguide (72) formed in the input waveguide part continuously with the input waveguide. The output waveguide includes an another taper section having such an inclination that the light input in the backward direction is not coupled into the input portion.
    Alternatively the output region is constructed differently but always such that light input in the backward direction is not coupled into the input portion. An optical signal is transmitted in a forward direction from the input portion to the output portion and is not transmitted in a backward direction from the output portion to the input portion.

    摘要： An image display apparatus (1000) is provided to improve display characteristics, the apparatus including a prism (300) and a pixel section (400) on one side of the prism (300). The pixel section (400) includes a reflective electrode (410) and dielectrics (420) disposed at a predetermined distance from the reflective electrode (410). The dielectrics (420) are in contact with the reflective electrode (410) if voltage is applied, and the effective refractive index changes according to the image signal. The effective refractive index of the section of the reflective electrode (410) in contact with the dielectrics (420) changes, and accordingly, the reflectivity of the reflective electrode (410) changes corresponding to the image signal. The pixel section (400) is able to regulate the surface plasmon resonance by regulating the reflective electrode (410), and is able to display the black state using the surface plasmon resonance. The image display apparatus (1000) provides improved contrast ratio by preventing color leaks from arising in the black state, and thus, improve display characteristics.
