    摘要: An optical waveguide element having a directional coupler is disclosed. The element includes a first and a second waveguide located adjacent to each other at a predetermined portion for mode coupling, a first dummy waveguide extending from an one end of the second waveguide, a reflector installed on an end surface of the first dummy waveguide, and a second dummy waveguide located adjacent to the first dummy waveguide at a predetermined portion for a mode coupling. The optical signals progressing from the second dummy waveguide to the first dummy waveguide disappear while sequentially passing through the reflector and the second dummy waveguide. In the optical waveguide element, optical signals passing through the first dummy waveguide gradually disappear while passing through the reflector and the second dummy waveguide, thereby improving a bi-directional cross-talk.

    摘要: A key pad lighting apparatus for a portable terminal includes: a waveguide in which a plurality of key buttons are arranged at one surface thereof; at least one light source provided at one side of the waveguide for introducing the light into the waveguide; and a guide member surrounding the light source for preventing a discharge of the light and for guiding the light into the waveguide. The key pad lighting apparatus can uniformly illuminate the key buttons installed in the key pad with a few light source using less light sources which helps to reduce the power consumption.
