Abstract
An optical component may comprise a horizontal member with two side walls and a substantially transparent end wall protruding from the horizontal member. The end wall, side walls and horizontal member may partially enclose an interior volume, and optical functionality is imparted in any suitable manner on at least a portion of the end wall. An optical assembly may comprise such an optical component mounted on a waveguide substrate along with a planar waveguide and a second waveguide, which are end-coupled by either reflection from the optical component end wall or transmission through the optical component end wall. An end portion of a planar waveguide may be received within the interior volume of the mounted component. Proper positioning of the optical component relative to the waveguides may be facilitated by alignment surfaces and/or alignment marks on the component and/or waveguide substrate.
