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

摘要

is the optical element, the first transmitting surface and a second transmitting surface opposed to each other, the first transmitting surface and a second substantially flat mounting surface is arranged between the transmission side, one or more alignment mark, and comprises a substantially transparent material having an optical coating. The optical element is arranged to be self-supported on a waveguide substrate having a substantially flat mounting surface on the corresponding portion of the substantially flat substrate surface. The alignment marks of the optical element is substantially aligned with the alignment marks on the waveguide substrate, a waveguide on the substrate may be coupled to the first end by a reflection from the transmission side. Transmitting surface and the permeate side of the mounting surface is disposed so as to be positioned in a relative orientation relative to the substrate surface, in the future, if the above light beam to enter the optical element substantially parallel to and passing through the first optical element to the substrate surface side tumyeon as a light beam passing through is arranged into place, and leaves the optical element through the second transmitting surface. The optical element may further include a lens or aperture. ;
