Abstract

A coupling apparatus includes a lens disposed between a port, such as a photodetector, and a light source, such as a fiber. The lens is aligned such that light emitted from the light source is focused by the lens onto the port. Between the lens and light source and/or lens and port, a low contrast medium is disposed to reduce reflection that could degrade signal strength.
