An optical coupler. The coupler has an optical element for transferring an optical signal from an entrance region, external to the optical unit, to an exit region, also external to the optical unit. The coupling element has a first substantially planar transmitting surface lying in a first plane, a second substantially planar transmitting surface lying in a second plane not coplanar with the first plane, a first substantially planar reflecting surface substantially perpendicular to the first transmitting surface, and a second substantially planar reflecting surface substantially parallel to the first reflecting surface, and a shaped reflecting surface substantially perpendicular to and adjoining the first and second reflecting surfaces.
