Abstract
The present invention is directed towards a back-reflection reduction device that is disposed between a support structure containing a plurality of optical waveguides and a bulk media. The support structure containing the optical waveguides has a substantially flat end face at which the optical waveguides terminate. Where the optical waveguides intersect the end face, they are substantially perpendicular to it. The back-reflection reduction device comprises a window disposed between the bulk media and the support structure. The window has a refractive index that is substantially identical to that of the optical waveguides. The window has an inner side that is affixed to the support structure and an opposing outer side. A gap exists between the window outer side and the bulk media. The gap provides an index of refraction substantially equal to unity.
