Abstract
This invention provides optical waveguide, transmitting, and receiving devices and methods that enables bidirectional communication. Formed on an optical waveguide near a first end (A-side) to cross a direction of light propagation may be a trench-shaped space having a first boundary surface and a second boundary surface. The first boundary surface may internally reflect the light propagating through the optical waveguide from a second end (B-side) so that the reflected light may exit outward through a side surface of the optical waveguide. The transmitting light entering through an end surface on the A-side of the optical waveguide may pass through the second boundary surface and enter through the first boundary surface. In the optical waveguide formed on a substrate, the optical signal may be bidirectionally transmitted and received by a relatively simple constitution to achieve an increase in density of optical wiring.
