OPTICAL ELEMENT FOR FREE-SPACE PROPAGATION BETWEEN AN OPTICAL WAVEGUIDE AND ANOTHER OPTICAL WAVEGUIDE, COMPONENT, OR DEVICE

摘要

The optical element has a first transmitting surface and a second transmitting surface, a first transmitting surface and a substantially transparent material having a surface substantially flat mounting disposed between the second transmitting surface, one or more alignment mark, and the optical coating facing each other It comprises a. The optical element is disposed so that self-supporting on a waveguide substrate having a substantially flat mounting surface on the substantially flat portion of the corresponding substrate surface. The alignment marks of the optical element is substantially aligned with the alignment mark on the waveguide substrate, a waveguide on the substrate may be coupled to end by the reflection from the first transmitting surface. If the permeate side and the mounting is arranged to be located by transmission relative orientation on the substrate surface side, substantially parallel to the passage, and the first of the above through tumyeon surface side to come the light beam entering the optical element optical element to the substrate surface passing a light beam through the optical element and is arranged Clicker out through the second transmitting surface. The optical element may further include a lens or aperture.
