  • Publication number: 20110090564
    Abstract: An exterior part (100) has a first structural color region (111) formed by a first linear peak-valley pattern including multiple linear grooves arranged in X direction, and a second structural color region (112) formed by a second linear peak-valley pattern including multiple linear grooves arranged in Y direction. The widths, depths, and pitches of the linear grooves are dimensions enabling the generation of diffracted light including structural colors. In the first structural color region (111), surfaces inclined in X direction (3 o'clock or 9 o'clock direction) are formed. In the second structural color region (112), surfaces inclined in Y direction (0 o'clock or 6 o'clock direction) are formed.

  • Publication number: 20110026208
    Abstract: On a triangular groove array structure 53 with a constant structure period, first structural color regions 51 and a second structural color region 52 are formed. The first structural color regions 51 are covered with a protective layer 54 having a refractive index N and the second structural color region 52 is directly exposed to an air layer 55. Variations in color development characteristics owing to the influence of the protective layer 54 can bring the pattern and character of the second structural color region 52 into relief with a contrast.

  • Patent number: 6947645
    Abstract: An optical package substrate and a molding method therefor which provide for easy production, easy mounting of optical elements such as photodiodes and lasers, good functionality, productivity and economy, and an optical device incorporating the package substrate. On the surface of an optical package substrate, a guide groove used for the positioning of an optical fiber and a tapered face adjoining the guide groove are provided, the tapered face being formed to have a predetermined angle. A mirror for reflecting light is formed on the tapered face. An optical fiber is affixed in the guide groove. A surface reception type photodiode, which is placed in a position for receiving light deflected by the mirror, is mounted above the tapered face. By providing a positioning marker for a light receiving element on the optical package substrate, it becomes particularly easy to mount the surface reception type photodiode through passive alignment.
