    摘要： A planar light wave circuit is disclosed, which comprises: a first waveguide for receiving optical signals from an outside; a second waveguide having a first end surface and a second end surface, so that lights outputted from the first waveguide are partially reflected by the first end surface and are partially incidented into the first end surface and then outputted through the second end surface; a third waveguide for receiving the light reflected by the first end surface; and a common region bordering each end surface of the first to the third waveguides and having an index of refraction different from an index of refraction of the second waveguide.

    摘要： Disclosed is a keypad which can realize uniform and bright illumination, small power consumption and low manufacturing cost. The keypad includes a light guide layer through which light travels, at least one key button disposed on an upper surface of the light guide layer, a lower elastic layer disposed on a lower surface of the light guide layer, located opposite the upper surface, and at least one reflective pattern formed on the light guide layer and partially reflecting light traveling through the light guide layer toward the key button.
