Abstract: A method of providing image-associated information by an image-associated information providing apparatus includes receiving broadcasting image information from a mobile device, searching an object that matches the broadcasting image information, extracting image-associated information that matches the found object and transmitting the extracted image-associated information to the mobile device.

Abstract: An easy method proposes a passive alignment by using an alignment mark. That is, V-shaped grooves are utilized as alignment marks in place of a metal pattern of the prior art in observing an optical contrast. Also, in order to adjust a height of an optical device, the support made of a metal is formed in the conventional method, whereas in the present invention a height of an optical device is adjusted by etching the silicon substrate and clamped through the use of solder bumps formed in the V-shaped grooves. And also, in this invention, it is possible that V-shaped grooves can be facilely formed on a non-planarized substrate by using a method of burying a mask material during the formation of the V-shaped grooves. By applying the above principle, the present invention proposes a process capable of passive aligning an optical device, a planar lightwave circuit (PLC) and an optical fiber, simultaneously.
